Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] Synchrotron radiation sources, as cutting-edge "photon probes" for detecting the microstructure and dynamic processes of matter, are core infrastructure supporting breakthroughs and technological innovations in fields such as materials science, life sciences, condensed matter physics, chemical engineering, and advanced manufacturing.

[0027] Monochromator is a key component in synchrotron radiation sources. It uses the atomic crystal planes of crystals as natural optical diffraction gratings. Based on the Bragg diffraction principle, it can precisely filter out monochromatic light with a specific wavelength (energy) and extremely high energy resolution from the broadband continuous high-power "white light" generated by the source.

[0028] When synchrotron radiation is incident on the first crystal of the monochromator, it will cause the first crystal to undergo large thermal deformation, which will greatly reduce the output performance of the monochromator, decrease the parallelism between the two crystals, and affect the experimental accuracy.

[0029] In related technologies, low-temperature cooling methods are commonly used to cool the first crystal in order to control its thermal deformation. Examples of such cooling methods include edge cooling, bottom cooling, and microchannel cooling. However, these methods have low heat exchange efficiency and poor cooling effect.

[0030] Based on this, the present invention proposes a crystal assembly in which a first pipeline with at least three sub-pipelines is provided between the first pressure plate and the first cooling block, and / or between the second pressure plate and the second cooling block, and the at least three sub-pipelines are arranged at intervals along the second direction. This increases the number of pipelines arranged between the first cooling block and the first pressure plate, and / or between the second pressure plate and the second cooling block, thereby significantly improving the heat exchange efficiency, making the heat dissipation of the first cooling block and / or the second cooling block more uniform, reducing the temperature gradient, increasing the heat dissipation capacity of the first crystal, effectively reducing the thermal deformation of the first crystal, and helping to improve the stability of the first crystal.

[0031] The following is combined Figures 1 to 3 The crystal assembly 1 and monochromator of the present invention are described.

[0032] Firstly, such as Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a crystal assembly 1, including a first crystal 10, a first cooling block 20, a second cooling block 30, a clamping assembly 40, and a cooling pipe 50. Along a first direction X, the first cooling block 20 and the second cooling block 30 are respectively disposed at both ends of the first crystal 10. The clamping assembly 40 includes a first pressure plate 41 and a second pressure plate 42. The first pressure plate 41 is disposed on the side of the first cooling block 20 opposite to the first crystal 10. The second pressure plate 42 is disposed on the side of the second cooling block 30 opposite to the first crystal 10. The cooling pipe 50 includes a first pipe 51. At least a portion of the first pipe 51 is disposed between the first cooling block 20 and the first pressure plate 41, and / or, at least a portion of the first pipe 51 is disposed between the second cooling block 30 and the second pressure plate 42. The first pipe 51 includes at least three sub-pipes 512. The at least three sub-pipes 512 are arranged at intervals along a second direction Z. The second direction Z intersects the first direction X.

[0033] In this embodiment, at least a portion of the first conduit 51 is disposed between the first cooling block 20 and the first pressure plate 41. Alternatively, at least a portion of the first conduit 51 is disposed between the second cooling block 30 and the second pressure plate 42. Alternatively, there are two first conduits 51, with at least a portion of one first conduit 51 disposed between the first pressure plate 41 and the first cooling block 20, and at least a portion of the other first conduit 51 disposed between the second pressure plate 42 and the second cooling block 30.

[0034] Since the first pipe 51 includes at least three sub-pipes 512, and the at least three sub-pipes 512 are arranged at intervals along the second direction Z, the number of pipes arranged between the first cooling block 20 and the first pressure plate 41, and / or between the second pressure plate 42 and the second cooling block 30 is increased, thereby significantly improving the heat exchange efficiency, making the heat dissipation of the first cooling block 20 and / or the second cooling block 30 more uniform, reducing the temperature gradient, increasing the heat dissipation capacity of the first crystal 10, effectively reducing the thermal deformation of the first crystal 10, and helping to improve the stability of the first crystal 10.

[0035] Optionally, the cooling medium in the cooling pipe 50 includes water, that is, the first crystal 10 is cooled by water, which has the advantages of low cost and good chemical stability.

[0036] Optionally, the number of sub-pipes 512 is three, four or five, which can improve the cooling capacity of the first crystal 10 while making full use of the side space of the first cooling block 20 or the second cooling block 30.

[0037] Optionally, the first cooling block 20 is a copper block, and the second cooling block 30 is a copper block.

[0038] Optionally, the first pressure plate 41 is made of stainless steel, and the second pressure plate 42 is made of stainless steel.

[0039] Optionally, the crystal assembly 1 further includes an indium sheet disposed between the first crystal 10 and the first cooling block 20, and / or, the indium sheet is disposed between the first crystal 10 and the second cooling block 30.

[0040] Optionally, the first direction X is the width direction of the first crystal 10, and the second direction Z is the height direction of the first crystal 10.

[0041] In some embodiments, the first conduit 51 is bent multiple times to form at least three sub-conduits 512.

[0042] In other words, at least three sub-pipes 512 are repeatedly bent from a single pipe and sandwiched between the first cooling block 20 and the first pressure plate 41, and / or sandwiched between the second pressure plate 42 and the second cooling block 30. That is, the pipes set between the first cooling block 20 and the first pressure plate 41, and / or between the second pressure plate 42 and the second cooling block 30 are single-path, unbranched pipes. This can significantly improve heat exchange efficiency while reducing fluid vibration in the cooling pipe 50, avoiding beam jitter, ensuring energy resolution, and improving the stability and reliability of the monochromator.

[0043] Moreover, the fact that at least three sub-circuits 512 are formed by multiple bends of a single tube helps to reduce manufacturing difficulty, simplify the manufacturing process, and thus reduce the production cost of the monochromator.

[0044] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the first pipeline 51 also includes a bend 514, through which any two adjacent sub-pipes 512 are connected. The bend 514 is arc-shaped; and / or, the connection between the bend 514 and any sub-pipe 512 is arc-shaped.

[0045] In this embodiment, the bend 514 between any two adjacent sub-pipes 512 is arc-shaped, and / or, the connection between the bend 514 between any two adjacent sub-pipes 512 and any sub-pipe 512 is arc-shaped. That is, the rounded transition at the bend of the first pipe 51 makes the fluid in the cooling pipe 50 flow more smoothly, which helps to further reduce fluid vibration and improve the stability of the monochromator. Furthermore, the rounded transition at the bend of the first pipe 51 also facilitates the processing of the first pipe 51.

[0046] In some embodiments, such as Figure 1 and Figure 2As shown, there are two first pipes 51. At least a portion of one first pipe 51 is located between the first cooling block 20 and the first pressure plate 41, and at least a portion of the other first pipe 51 is located between the second cooling block 30 and the second pressure plate 42. The cooling pipe 50 also includes a second pipe 52, one end of which is connected to the inlet of one of the first pipes 51, and the other end of which is connected to the outlet of the other first pipe 51. The hardness of the second pipe 52 is less than the hardness of either of the first pipes 51.

[0047] In this embodiment, the outlet of one of the first pipes 51 and the inlet of the other first pipe 51 are respectively connected to the two ends of the second pipe 52, so that the two first pipes 51 and the second pipe 52 form a single path and a pipe loop without branches, which can significantly improve the heat exchange efficiency while reducing fluid vibration in the cooling pipe 50 and improving the stability of the monochromator.

[0048] In addition, the hardness of the second pipe 52 is less than that of any of the first pipes 51. That is to say, the second pipe 52 is a flexible pipe and the first pipe 51 is a rigid pipe, which facilitates pipe installation and allows for greater installation position deviation, thereby reducing installation difficulty and improving installation efficiency.

[0049] Moreover, since the two first pipes 51 are connected by a flexible hose, it can act as a buffer during fluid flow, which helps to further reduce fluid vibration.

[0050] Optionally, the first pipe 51 and the second pipe 52 are connected in a sealed manner via an adapter.

[0051] Optionally, the first conduit 51 is a stainless steel conduit.

[0052] Optionally, the second conduit 52 is a flexible metal conduit, such as a copper conduit.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the cooling pipe 50 also includes an inlet pipe 53 and a return pipe 54. The inlet pipe 53 is connected to one of the first pipes 51 via a third pipe 55. The return pipe 54 is connected to the other first pipe 51 via a fourth pipe 56. At least one of the third pipe 55 and the fourth pipe 56 has a lower hardness than either of the first pipes 51.

[0054] In this embodiment, the cooling pipe 50 is further defined as including an inlet pipe 53 and a return pipe 54. Specifically, the inlet pipe 53 is connected to the inlet of one of the first pipes 51 via a third pipe 55, the outlet of the first pipe 51 is connected to the inlet of another first pipe 51 via a second pipe 52, and the outlet of the other first pipe 51 is connected to the return pipe 54 via a fourth pipe 56. This allows the two first pipes 51, the second pipe 52, the third pipe 55, the fourth pipe 56, the inlet pipe 53, and the return pipe 54 to form a single-path, unbranched pipe loop, which can significantly improve heat exchange efficiency while further reducing fluid vibration within the cooling pipe 50.

[0055] The hardness of the third pipe 55 is less than the hardness of any of the first pipes 51, that is, the third pipe 55 is a flexible pipe and the first pipe 51 is a rigid pipe, and / or the hardness of the fourth pipe 56 is less than the hardness of any of the first pipes 51, that is, the fourth pipe 56 is a flexible pipe and the first pipe 51 is a rigid pipe. This facilitates pipe installation and allows for greater installation position deviation, which helps to reduce installation difficulty and improve installation efficiency.

[0056] Furthermore, since the first pipe 51 and the inlet pipe 53 are connected by a flexible hose, and / or the first pipe 51 and the return pipe 54 are connected by a flexible hose, it can play a buffering role in the fluid flow process, which is beneficial to further reduce fluid vibration.

[0057] Optionally, the third pipeline 55 is sealed to the first pipeline 51 and the inlet pipe 53 via an adapter.

[0058] Optionally, the fourth pipeline 56 is sealed to the first pipeline 51 and the return pipeline 54 via an adapter.

[0059] In some embodiments, such as Figure 2 As shown, at least one of the inlet pipe 53 and the return pipe 54 includes a first pipe section 57, a second pipe section 58, and a connecting pipe section 59. The connecting pipe section 59 is located between the first pipe section 57 and the second pipe section 58. Both ends of the connecting pipe section 59 are connected to the first pipe section 57 and the second pipe section 58, respectively. The hardness of at least one of the first pipe section 57 and the second pipe section 58 is greater than the hardness of the connecting pipe section 59.

[0060] In this embodiment, at least one of the inlet pipe 53 and the return pipe 54 is defined to include a first pipe segment 57, a second pipe segment 58, and a connecting pipe segment 59. Specifically, one end of the connecting pipe is connected to the first pipe segment 57, and the other end is connected to the second pipe segment 58. Since the connecting pipe segment 59 is a flexible hose, that is, the first pipe segment 57 and the second pipe segment 58 are connected by a flexible hose, which facilitates the installation of the pipe and allows for a larger installation position deviation, which helps to reduce the installation difficulty and improve the installation efficiency.

[0061] Moreover, since the first pipe section 57 and the second pipe section 58 are connected by a flexible hose, it can play a buffering role during fluid flow, which helps to further reduce fluid vibration.

[0062] It is understandable that, in the case where the inlet pipe 53 includes a first pipe section 57, a second pipe section 58, and a connecting pipe section 59, the first pipe section 57 is connected to the third pipe 55. In the case where the return pipe 54 includes a first pipe section 57, a second pipe section 58, and a connecting pipe section 59, the first pipe section 57 is connected to the fourth pipe 56.

[0063] In some embodiments, such as Figure 1 As shown, the crystal assembly 1 also includes a backplate 60 and a first heat-conducting plate 70. One end of the first heat-conducting plate 70 is disposed in at least one of the liquid inlet pipe 53 and the liquid return pipe 54, and the other end of the first heat-conducting plate 70 is disposed in the backplate 60.

[0064] In this embodiment, one end of the first heat-conducting plate 70 is located in the liquid inlet pipe 53. Alternatively, one end of the first heat-conducting plate 70 is located in the liquid return pipe 54. Alternatively, there are two first heat-conducting plates 70, one in the liquid inlet pipe 53 and the other in the liquid return pipe 54. Alternatively, there are multiple first heat-conducting plates 70, all of which are located in either the liquid inlet pipe 53 or the liquid return pipe 54. The specific configuration can be adjusted according to actual needs.

[0065] Since the other end of the first heat-conducting plate 70 is located on the back plate 60, the cooling effect of the entire system can be improved.

[0066] Optionally, the first crystal 10, the first cooling block 20, the second cooling block 30, and the clamping assembly 40 are integrally fixed to the back plate 60.

[0067] Optionally, the first heat-conducting plate 70 is fixed to the liquid inlet pipe 53 and / or the liquid return pipe 54 by a clamping mechanism.

[0068] Optionally, the first heat-conducting sheet 70 is copper foil.

[0069] In some embodiments, such as Figure 1 and Figure 2 As shown, the crystal assembly 1 also includes a sealing cap assembly 80, a first connector 90, and a second connector 100. The inlet pipe 53 and the return pipe 54 are respectively connected to one side of the sealing cap assembly 80. The first connector 90 and the second connector 100 are respectively located on the other side of the sealing cap assembly 80; the first connector 90 is connected to the inlet pipe 53, and the second connector 100 is connected to the return pipe 54.

[0070] In this embodiment, the crystal assembly 1 is further defined as including a sealing cap assembly 80, a first connector 90, and a second connector 100. Specifically, the liquid inlet pipe 53 and the liquid return pipe 54 are respectively connected to one side of the sealing cap assembly 80, and the first connector 90 and the second connector 100 are respectively connected to the other side of the sealing cap assembly 80. It can be understood that the first connector 90 and the second connector 100 are respectively connected to a chiller, thereby providing cooling water to the entire cooling pipeline 50, achieving the purpose of cooling the first crystal 10, controlling the thermal deformation of the first crystal 10, and thus helping to improve the experimental accuracy.

[0071] Optionally, either the first connector 90 or the second connector 100 is a pagoda-type connector.

[0072] In some embodiments, such as Figure 1 and Figure 2 As shown, the sealing cap assembly 80 includes an inner sealing cap 82, an end cap 84, and a sealing element. An inlet pipe 53 and a return pipe 54 are respectively connected to the inner sealing cap 82. The end cap 84 is located on the side of the inner sealing cap 82 opposite to the first crystal 10. A first connector 90 and a second connector 100 are respectively connected to the end cap 84. The sealing element is located between the end cap 84 and the inner sealing cap 82.

[0073] In this embodiment, the sealing cap assembly 80 is defined to include an inner sealing cap 82, an end cap 84, and a sealing element. Specifically, since a sealing element is provided between the end cap 84 and the inner sealing cap 82, it is beneficial to improve the sealing performance of the inlet pipe 53 and the return pipe 54 at the joint.

[0074] Optionally, the seal includes a sealing ring.

[0075] In some embodiments, the first conduit 51 is a stainless steel conduit.

[0076] In other words, the first pipe 51 is made of stainless steel. Compared with copper pipes, stainless steel pipes can have thinner walls, thereby increasing the flow area of ​​the first pipe 51, increasing the fluid flow rate, and improving the cooling capacity of the first crystal 10.

[0077] Moreover, since stainless steel pipes can have thinner walls, the outer diameter of the pipes can be reduced accordingly, thereby reducing the space occupied by the pipes. More sub-pipes 512 can be arranged on the side of the first cooling block 20 and / or the second cooling block 30, which is beneficial to further improve the cooling effect.

[0078] In addition, stainless steel has better pressure resistance, ensuring that the first pipe 51 can withstand the pressure of cooling water, which helps to extend the service life of the cooling pipe 50.

[0079] In some embodiments, such as Figure 3As shown, the crystal assembly 1 also includes a cooling channel 110, through which a first conduit 51 passes. Where at least a portion of the first conduit 51 is located between the first cooling block 20 and the first pressure plate 41, the cooling channel 110 is located between at least one of the first cooling block 20 and the first pressure plate 41. Where at least a portion of the first conduit 51 is located between the second cooling block 30 and the second pressure plate 42, the cooling channel 110 is located between at least one of the second cooling block 30 and the second pressure plate 42.

[0080] In this embodiment, since the first pipe 51 passes through the cooling channel 110, that is, a part of the first pipe 51 is buried between the first pressure plate 41 and the first cooling block 20, and / or a part of the first pipe 51 is buried between the second pressure plate 42 and the second cooling block 30, compared with the related technology of opening a channel for fluid to flow inside the cooling copper block, it is beneficial to improve the sealing of the entire cooling circuit and facilitates increasing the number of sub-pipes 512, thereby improving the cooling effect on the first crystal 10.

[0081] When at least a portion of the first pipe 51 is located between the first cooling block 20 and the first pressure plate 41, specifically, the cooling channel 110 is located on the first pressure plate 41, or the cooling channel 110 is located on the first cooling block 20, or a portion of the cooling channel 110 is located on the first pressure plate 41 and another portion is located on the first cooling block 20.

[0082] It is understandable that part of the cooling channel 110 is set on the first pressure plate 41 and another part is set on the first cooling block 20. This arrangement facilitates the processing of the cooling channel 110 and the installation of the first pipe 51.

[0083] When at least a portion of the first pipe 51 is located between the second cooling block 30 and the second pressure plate 42, specifically, the cooling channel 110 is located on the second pressure plate 42, or the cooling channel 110 is located on the second cooling block 30, or a portion of the cooling channel 110 is located on the second pressure plate 42 and another portion is located on the second cooling block 30.

[0084] It is understandable that part of the cooling channel 110 is set on the second pressure plate 42 and another part is set on the second cooling block 30. This arrangement facilitates the processing of the cooling channel 110 and the installation of the first pipe 51.

[0085] In some embodiments, such as Figure 1As shown, the crystal assembly 1 also includes a second crystal 120, a mounting base 130, a mounting plate 140, and a plurality of second heat-conducting plates 150. The mounting base 130 is disposed on one of the sub-channels 512. The mounting plate 140 is connected to one side of the mounting base 130 back to the ion channel 512. One end of each of the plurality of second heat-conducting plates 150 is connected to the mounting plate 140, and the other end of each of the plurality of second heat-conducting plates 150 is disposed on the second crystal 120.

[0086] In this embodiment, the crystal assembly 1 is further defined as including a second crystal 120, a mounting base 130, a mounting plate 140, and a plurality of second heat-conducting sheets 150. Specifically, one end of the plurality of second heat-conducting sheets 150 is connected to the mounting plate 140, and the other end is disposed on the second crystal 120. It can transfer the heat of the second crystal 120 to the sub-pipe 512, thereby carrying away the heat during the fluid flow and achieving the cooling of the second crystal 120.

[0087] Optionally, the mounting base 130 is a copper block. The mounting plate 140 is a copper plate.

[0088] Optionally, the second heat-conducting sheet 150 is copper foil.

[0089] Optionally, the mounting plate 140 is provided with mounting grooves, and one end of each of the plurality of second heat-conducting plates 150 is respectively disposed in the mounting grooves.

[0090] In some embodiments, such as Figure 2 As shown, the clamping assembly 40 also includes a connecting rod 43, a first fastener 44, a second fastener 45, and an elastic element 46. The two ends of the connecting rod 43 pass through the first pressure plate 41 and the second pressure plate 42, respectively. The first fastener 44 is located on the side of the first pressure plate 41 opposite to the first crystal 10 and is connected to the connecting rod 43. The second fastener 45 is located on the side of the second pressure plate 42 opposite to the first crystal 10 and is connected to the connecting rod 43. The elastic element 46 is disposed between the first pressure plate 41 and the first fastener 44, and / or, the elastic element 46 is disposed between the second pressure plate 42 and the second fastener 45.

[0091] In this embodiment, the clamping assembly 40 is further defined as including a connecting rod 43, a first fastener 44, a second fastener 45, and an elastic element 46. Specifically, since the elastic element 46 is provided between the first pressure plate 41 and the first fastener 44, and / or between the second pressure plate 42 and the second fastener 45, a controllable and uniform clamping force can be applied to the first crystal 10, causing the indium sheet located between the first crystal 10 and the first cooling block 20, and between the first crystal 10 and the second cooling block 30, to undergo plastic deformation, and fully fill the microscopic gaps between the first crystal 10 and the first cooling block 20, and between the first crystal 10 and the second cooling block 30. By utilizing the high thermal conductivity of the indium sheet, the contact thermal resistance is further reduced and the thermal conductivity is improved.

[0092] Optionally, the elastic element 46 includes a disc spring assembly.

[0093] In a specific embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the crystal clamping cooling structure (crystal assembly 1) mainly includes an indium sheet, a cooling copper block (first cooling block 20 and second cooling block 30), a cooling pipe 50, a crystal pressure plate (first pressure plate 41 and second pressure plate 42), a pressure plate connecting rod (connecting rod 43), a disc spring assembly (elastic element 46), a sealing cover (sealing cover assembly 80), and a pagoda-shaped connector (first connector 90 and second connector 100).

[0094] The crystal (first crystal 10) has an indium sheet, a cooling copper block, and a crystal pressure plate on both sides. A controllable and uniform clamping force is applied through the pressure plate connecting rod and the disc spring assembly, causing the indium sheet to undergo plastic deformation and fully fill the micro gap between the crystal and the cooling copper block. The high thermal conductivity of the indium sheet is used to further reduce the contact thermal resistance and improve the thermal conductivity efficiency.

[0095] The cooling pipe 50 is welded to the copper blocks (first cooling block 20 and second cooling block 30). Four cooling water circuits (sub-pipes 512) are evenly arranged on each side of the copper block, making the heat dissipation of the copper block more uniform, reducing the temperature gradient, and reducing the thermal deformation of the crystal (first crystal 10). The heat dissipation capacity is increased by winding the pipes multiple times. Moreover, compared with microchannels, this single-path, branchless pipe can further reduce vibration.

[0096] The bends in the circuit (bend 514) are connected by gentle rounded corners to reduce fluid vibration and facilitate pipe bending.

[0097] The piping (first piping 51) is made of stainless steel, which allows for thinner walls compared to copper pipes, further reducing the space occupied by the piping. Stainless steel also has better pressure resistance, ensuring that the piping can withstand the pressure of cooling water. The piping within the vacuum chamber has no sealed joints and is entirely welded using argon arc welding to prevent leaks and provides pressure and corrosion resistance.

[0098] In the straight section (sub-pipe 512) of the stainless steel pipe extending from the cooling copper block, a small copper block (mounting base 130) is welded to the side near the crystal (second crystal 120) to serve as the base for the copper foil mounting plate (mounting plate 140). An elongated groove (mounting slot) is cut into the copper foil mounting plate to insert and press the copper foil (second heat-conducting plate 150) into place. The copper foil mounting plate is fixed to the base (mounting base 130) with screws to cool the second crystal (second crystal 120).

[0099] The cooling piping 50 consists of both stainless steel rigid pipes and metal flexible hoses, making installation easier and allowing for greater installation position deviations. The stainless steel pipes and metal flexible hoses are connected by adapters and fixed by welding.

[0100] The copper foil (first heat-conducting plate 70) is fixed with a clamping mechanism in the straight section of the stainless steel water pipe (inlet pipe 53 and / or return pipe 54), and the other end of the copper foil is fixed to the back plate 60 by a pressure plate, so that the cooling effect of the whole system is better.

[0101] The inlet and outlet are connected to the inner cover 82 by welding. The inner cover 82 forms a seal with the main shaft end cover flange (end cover 84) through an O-ring (seal). Two pagoda-shaped connectors (first connector 90 and second connector 100) are welded to the pipeline port for connecting to the chiller.

[0102] The above design can increase the heat exchange efficiency of the side-cooling scheme, reduce the temperature gradient on the crystal (first crystal 10), and reduce fluid vibration.

[0103] Secondly, this embodiment provides a monochromator, including the crystal component 1 of the first aspect embodiment described above. Since the monochromator shown in this embodiment includes the crystal component 1 of the first aspect embodiment, it possesses all the beneficial technical effects of the crystal component 1, which will not be elaborated further here.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
