The invention provides a laser light source, a related light emitting device and a related lamp. The laser light source comprise a laser emitting source for emitting a laser, a first gathering deviceand a second gathering device, wherein each of the first gathering device and the second gathering device is a ball lens or a ball lens set. The laser light source further comprises a fluorescent device located on the optical axis of the second side of the second gathering device, the distance between the fluorescent device and the main face of the second gathering device is smaller than the minimum focal length of the second gathering device, wherein A is larger than or equal to 50 degrees. After sequentially passing through the first gathering device and the second gathering device from theposition near the optical axis, the laser is focused to the fluorescent device, and the fluorescent device generates a received laser. The full spherical surface design is adopted in the second gathering device, the fluorescent device is placed at the proper position within the focus of the second gathering device, emitted light can still be orderly but not crossed, and accordingly the needed optics purpose can be achieved through the rear end optical design. By means of the first gathering device, the focus of the laser incident near the optical axis can be moved forwards to the position of the fluorescent device.

The invention discloses a three-dimensional mammary gland ultrasound image partition method based on homoplasmon and partial energy. The method includes that the three-dimensional mammary gland ultrasound image to be processed is inputted, the image to be processed is carried out an edge detection. A detected edge curved surface is carried out fitting. The homoplasmon and an overall energy functional are defined, and a numerical calculation is the last step. The three-dimensional mammary gland ultrasound image partition method based on homoplasmon and partial energy has the advantages that firstly, difficult problem that in the traditional method, a three dimensional neighboring window is hard to choose is solved, so that, the neighboring window is capable of varying together with the changes of spatial position of a voxel.The homoplasmon, to some extent, can guarantee that the neighborhood cannot step over an organization, can effectively differentiate the pixels with similar appearance but belonging to different organizations, and the homoplasmon is helpful for improving the extraction accuracy of the tumor outline. Secondly, defects that for a level set model based on the global information, the unevenness of the gray level is hard to overcome and a level set model based on the partial regional information is fallen into the local extremum are solved, the extraction.

The invention belongs to the technical field of anemometers, in particular to a wind speed monitor, which comprises a cylinder shell, a swinging mechanism, a wind measuring mechanism, a measuring module and a one-way damping telescopic rod, wherein the greater the rotating speed of a parabolic cone empty cup blown by the wind is, the shorter the distance of the parabolic cone empty cup stretchingout of the cylinder shell is, further the shorter the distance of the first rotating shaft stretching out of the cylinder shell is; thus, the vibration amplitude generated when the first rotating shaft is blown by the wind is smaller, so as to protect the first rotating shaft indirectly. When the parabolic cone empty cup is subjected to special large-scale wind blowing, the parabolic cone empty cup can completely stretch into the cylinder shell, so as to achieve the purpose of protecting the parabolic cone empty cup; in addition, when the wind outside is small, the parabolic cone empty cup canmove and restore out of the cylinder shell again to continue to measure the wind speed. The wind speed monitor in the invention has simple structure and good use effect.

The invention belongs to the technical field of anemometers, and particularly relates to an anemometer for weather monitoring. The anemometer comprises a casing, a swinging mechanism, a wind measuringmechanism, a hydraulic mechanism and a measuring module, wherein the larger the rotating speed of a parabolic cone empty cup blown by the wind, the shorter the distance from which the parabolic coneempty cup extends beyond the casing, and the shorter the distance from which a first rotating shaft extends out of the casing, the smaller the amplitude of the vibration generated when the first rotating shaft is blown by the wind, thereby indirectly protecting the first rotating shaft. When the parabolic cone empty cup is subjected to a special large-scale wind blowing, the parabolic cone empty cup can completely enter the casing, which achieves the purpose of protecting the parabolic cone empty cup. In addition, when the wind has dropped outside, the parabolic cone empty cup can move and reset from the casing again for continuous measurement of the wind speed.

The invention relates to a mobile isolation fence, which is characterized by comprising a rack body, wheels and a rack body support, wherein the rack body is composed of an upper transverse tube, a lower transverse tube and a longitudinal support tube, which are fixedly connected with one another; the wheels are installed at the bottom of the rack body. The mobile isolation fence has the advantages of not only being capable of effectively isolating and storing cargoes so as to guarantee the cargoes to be sorted clearly, but also being capable of effectively isolating the field so as to guarantee vehicles not to cross randomly to reduce traffic accidents. According to the invention, operators can push at site due to the rolling wheels fixedly connected at the front of the fence; the isolation fence can land directly through the rack body support at the rear of the fence, and the rack body support plays a role in locating; according to the characteristic of heavy wind in port operation site, the isolation fence is formed by welding metal tubes, thus preventing from being blown down by wind. Furthermore, the isolation fence is provided with a large end and a small end, so that the isolation fences can be connected in series when being stored, the occupied area is greatly reduced, and the isolation fence is convenient for overall transportation.

The invention discloses a double-channel pipe in pipe which comprises an inner pipe and an outer pipe; the outside diameter of the inner pipe is smaller than the inside diameter of the outer pipe; thetwo ends of the inner pipe are provided with an inner inlet sleeve and an inner outlet sleeve respectively; each of the inner inlet sleeve and an inner outlet sleeve is provided with at least two positioning strips; a water channel is reserved between adjacent positioning strips; the two ends of the outer pipe are provided with an outer inlet sleeve and an outer outlet sleeve respectively; a portion of each of the outer inlet sleeve and the outer outlet sleeve extends into the outer pipe and is provided with a clamping block; the clamping blocks are matched with the end surfaces of the positioning strips in a length direction respectively so as to prevent the inner pipe from moving towards an outlet direction relative to the outer pipe along an axis; a portion of the inner outlet sleeve extends out of the outer outlet sleeve and is provided with a clamping groove; and the clamping groove is provided with a clamping ring so as to prevent the inner pipe from moving towards am inlet direction relative to the outer pipe along the axis. The double-channel pipe in pipe has the advantages that the device has a simple structure, the inner pipe and the outer pipe can be quickly assembled,and two relatively independent double channels are formed so as to facilitate connection with a double-channel four-way pipe and a double-channel faucet.
