The invention provides a business flow generation method, and the method comprises the steps: obtaining business elements in a to-be-initiated business when a user initiates the business; matching with a target flow template corresponding to the business elements in a preset flow template matcher through combining with the business elements; and organizing a business flow corresponding to the business initiated by the user according to the target flow template. According to the invention, the flow template matcher is set in advance for obtaining the business elements in the business and matching with the flow template corresponding to the business elements. The method can achieve different flow templates according to different business elements, can meet the demands of diversified business flows, and is larger in expansion range.

The invention discloses a wireless channel model matching and correction method based on map information, comprising the following steps: carrying out drive test sampling on typical points within a planned area to obtain sampling data; acquiring map information within the planned area to obtain map data; Collect the working parameters of all base stations that can cover the planned area to obtain the collected data; collect the sampling data, map data and collected data to obtain the first data set; preprocess the first data set to obtain the second data set; The parameters of the regression matching model and the parameters of the classification matching model are determined according to the second data set; the final prediction values ​​corresponding to the wireless channel models of the non-sampling points within the planning area are obtained through the regression matching model and the classification matching model. The invention has the advantages of simple operation, full use of a typical statistical channel model, low computational complexity, wide application range, improved accuracy of the wireless propagation channel model, and the like.

The invention discloses a Micro-LED array device based on group III nitride semiconductors, which is etched to form an array fan-shaped mesa structure that penetrates the p-type GaN layer, the quantum well active layer, and reaches the n-type GaN layer, and the p-type array The electrodes are vapor-deposited on the p-type GaN layer of the fan-shaped array, and the n-type array electrodes are vapor-deposited on the n-type GaN layer, and the n-type array electrodes form barriers to isolate the fan-shaped mesas from each other. And discloses its preparation method. In the present invention, a retaining wall made of n-type electrodes is added between the light-emitting units of the Micro-LED fan-shaped table array. The problem of crosstalk between units is beneficial to realize individual control; the use of n-type electrode metal as a retaining wall and the use of p-type electrodes with a mesh structure increases the current expansion range and effectively improves luminous efficiency.

An X-ray grating imaging system and imaging method, the system comprising: a distributed X-ray source, which is perpendicular to the propagation direction of the X-ray and distributed along a direction parallel to the grating stripes; a fixed grating module, which is distributed along the propagation direction of the X-ray The direction setting includes a first grating and a second grating, the first grating and the second grating are parallel to each other and their relative positions are fixed; and an X-ray detector. A group of stepping exposure processes based on the distributed X-ray source can obtain the light intensity at each pixel when the scanned object is included or not, so that the attenuation, phase contrast and One or several types of dark field information can be used to reconstruct images, and the overall system has the advantages of high system stability, short scanning time, low radiation dose and clear imaging.

The invention relates to a multi-stage transmission provided with an input shaft (3), which is connected to a shiftable front-mounted planet gear set (10), with an output shaft (4), which is connected to a shiftable main planet gear set (20), and with a number of shifting elements (A to F) whose selective closing enables the shifting of at least six forward speeds without range shift. An output element of the front-mounted planet gear set (10) can be connected to a first input element of the main planet gear set (20) via a first shifting element (A) and can be connected to a second input element of the main planet gear set (20) via a second shifting element (B). The input shaft (3) can be connected to a third input element of the main planet gear set (20) via a fifth shifting element (E). Preferably, a sun gear (11) of the front-mounted planet gear set (10) can be fixed via a sixth shifting element (F) mounted on the side of the front-mounted planet gear set (10) facing away from the main planet gear set (20). The front-mounted planet gear set (10) is provided in the form of a Plus gearing having inner and outer planet gears (12, 13) whose webs (15, 16) are interconnected.

The invention discloses a titanium alloy drug release vascular stent, and relates to the field of vascular stents. The titanium alloy drug release vascular stent comprises a stent body, wherein the stent body is composed of a stent outer membrane and a stent inner membrane, the stent outer membrane and the stent inner membrane are made of a titanium alloy material and are of hollowed-out structures, the portion between the stent outer membrane and the stent inner membrane is filled with a soft body, and the outer surfaces of the left and right sides of the stent outer membrane are fixedly connected with outer protrusions. The titanium alloy drug release vascular stent has the advantages that an inner container is inflated to achieve the flexible expansion of the outer protrusions to bloodvessels, the expansion range is very wide, the adjustment is very convenient, the adjustment can be carried out according to the own situation of a patient, after the expansion is completed, inner protrusions are squeezed through the inner container, thereby squeezing medicine balls, so that drugs in the medicine balls are squeezed into the blood vessels, thereby achieving the drug therapy of theblood vessels, and the vascular stent not only can keep the blood flow of the lumens of the blood vessels smooth, but also can prevent restenosis of the blood vessels, and the practicability is high.
