A method for simulating temporomandibular joint (TMJ) surgery based on an artificial intelligence (AI) technology includes: obtaining temporal bone corners and a temporal bone edge contour in each TMJ image based on a motion synchronization degree of and a distance between any two corners in each TMJ image; obtaining a plurality of mandible corners and a mandible motion direction based on a distance between the temporal bone corners in each TMJ image and coordinates of the corners in the TMJ image in a coordinate system; obtaining a real mandible edge contour in each TMJ image based on an edge contour on which the mandible corners are located and the mandible motion direction in each TMJ image; and constructing a TMJ anatomical model based on the real mandible edge contours and the temporal bone edge contours in all TMJ images.

Disclosed is an infinite-stage fracturing sliding sleeve. The infinite-stage fracturing sliding sleeve includes an outer cylinder, an inner cylinder, a sliding cylinder, an elastic element and a counting mechanism, wherein the inner cylinder closes a fracturing hole on the outer cylinder, and a lower end of the sliding cylinder is provided with an elastic claw. When the number of fracturing balls is less than a preset value, the elastic claw of the sliding cylinder moves in a reduced diameter section and an expanded diameter section in the outer cylinder. After the fracturing sliding sleeve is adopted, the fracturing sliding sleeves of all stages may be driven to open by fracturing balls of the same size, and there is no size difference between the fracturing sliding sleeves of all stages, so that the number of fracturing stages is not limited.

A diffraction analysis device and a method for a full-field X-ray fluorescence imaging analysis are disclosed. The device includes a switching assembly, collimation assemblies, an X-ray source, an X-ray detector, a laser indicator, and a computer control system. The switching assembly combines with the collimation assemblies to achieve a functional effect that is previously achieved by two different types of devices through only one device by changing the positioning layout of the X-ray source and the X-ray detector. The full-field X-ray fluorescence imaging analysis can be realized, and the crystal phase composition information and the element distribution imaging information of the sample can be quickly obtained through the same device without scanning, which not only greatly improves the utilization rate of each assembly in the device, reduces the assemblies cost of the device, makes the device structure more compact, but also greatly improves the analysis efficiency and detection accuracy.
