This invention discloses a method and system for batch conversion of bulb flat steel interfaces into angle steel or T-sections. It utilizes the LISP programming language and dynamic block technology in AutoCAD software, and involves secondary development of functional modules capable of automatically identifying bulb flat steel and batch replacing it with angle steel or T-sections during the ship design phase. Different specifications and patch forms of profile interfaces are drawn on a computer and integrated into dynamic blocks for angle steel, T-sections, and bulb flat steel using dynamic block technology. The system automatically identifies various forms of bulb flat steel in the original drawings according to set rules, calculates the base point, web angle, and bulb head orientation of each bulb flat steel, and batch replaces them with dynamic blocks of the same attributes. A dynamic block modification interface is developed to quickly modify profile specifications and patch forms. This invention enables automatic identification and batch replacement of bulb flat steel with angle steel or T-sections during the ship design phase using a computer, reducing the amount of repetitive manual drawing work for designers and laying the foundation for subsequent rapid modification of aggregate types.

The invention provides a surface evaporation source and an evaporation method, and belongs to the technical field of displays. The surface evaporation source comprises an evaporation container and a micro-arc baffle, the micro-arc baffle is arranged at the top of the evaporation container, and the evaporation container internally comprises a main baffle, a scattering sheet, an evaporation material baffle and an evaporation material container which are sequentially arranged below the micro-arc baffle; the number of the evaporation material containers is 2n, the number of layers of the evaporation material baffles is n, and n is larger than 1. The scattering sheet has a through hole; a crystal oscillator probe is further arranged in the evaporation container and arranged on the inner side wall of the evaporation container, and the vertical height of the crystal oscillator probe is located between the scattering piece and the evaporation material baffle. According to the method, an indirect evaporation mode of an existing surface source technology is abandoned, a direct evaporation mode is adopted, operation is easy, and mass production is achieved. And the number of the evaporation material containers is limited to be 2n, and multi-material co-evaporation can be achieved.

The utility model provides a vacuum coating clamp, which relates to the technical field of clamps, and comprises a coating machine, a connecting rod, a fixed seat in bearing connection with the surface of the connecting rod, a support plate fixed on the side surface of the connecting rod, a second sliding chute arranged on the surface of the support plate, and a clamp in sliding connection with the inside of the second sliding chute, the middle portions of the two clamps are both in threaded connection with threaded rods, second bevel gears are fixed to the side faces of the threaded rods, and first bevel gears are meshed with the surfaces of the second bevel gears. The arc surface of the side wall of the clamp is driven to clamp a tank workpiece, the clamping force of the clamp can be adjusted, the clamp is suitable for workpieces of different specifications, the corresponding clamp does not need to be replaced frequently according to the workpieces, time and labor are saved, the contact area of the clamp and the coating surface of the workpiece is small, and the coating efficiency is improved.

This invention belongs to the field of biomedical technology, specifically relating to a method and kit for improving the sensitivity and specificity of circulating tumor cell (CTC) detection. The method first treats anticoagulated blood with erythrocyte lysis buffer, centrifuges to obtain a cell suspension (including leukocytes and circulating tumor cells); then, a radiosensitizer is added and the suspension is irradiated; next, single-cell gel electrophoresis is used to detect the degree of DNA damage in the test cells; finally, leukocytes and tumor cells are distinguished based on cell morphology using a fluorescence microscope or fluorescence scanner. This invention is the first to detect the number and type of circulating tumor cells (CTCs) in peripheral blood based on ionizing radiation and radiosensitization effects, according to the degree of DNA damage in tumor cells. Compared with existing technologies, this detection method and kit are not only simple and rapid, but also significantly improve detection sensitivity and specificity. Furthermore, it is independent of the physical properties of cells and tumor cell surface markers, requires a small sample volume, is highly versatile, and can detect CTCs in different types of solid tumors.
