Abstract: A surface flatness detecting device for single crystal square is provide. The device includes a clamping assembly and a detecting assembly. The clamping assembly has a first clamper and a second clamper, the first clamper and the second clamper are configured to clamp a first end and a second end of the single crystal square rod, respectively. The detecting assembly has a first detector and a second detector, the first detector and the second detector are configured to detect a first side and a second side of the single crystal square rod, respectively. After the first side and the second side are detected by the first detector and the second detector, respectively, the first clamper and the second clamper rotate the single crystal square rod by 90 degrees to detect a third side and a fourth side of the single crystal square rod.

Abstract: Disclosed is an automatic crystal collection process, including: placing a crystal collection cylinder on a movable platform, detecting a length of a single crystal bar, and selecting a descending distance of the movable platform according to the length of the single crystal bar; raising a furnace sub-chamber to an upper limit, rotating the sub-chamber to a position above the crystal collection cylinder, and lowering the single crystal bar into the crystal collection cylinder; cutting off a seed crystal when the single crystal bar is lowered to a distance, and moving the single crystal bar with the descending of the movable platform until the single crystal bar is collected completely; raising the crystal collection cylinder along with the single crystal bar therein to a target position by the movable platform after the single crystal bar is collected completely, and finishing the crystal collection process.

Abstract: Provided in the present application are an antibody-drug conjugate, and a preparation method therefor and the use thereof. The antibody drug conjugate has a structure as represented by the formula Ab-[M-L-E-D]x, and the drug is selected from an anti-tubulin agent, a DNA intercalator, a DNA topoisomerase inhibitor and a RNA polymerase inhibitor. The prepared antibody-drug conjugate has a better drug-to-antibody ratio, and has a good targeted killing effect on colon cancer and non-small cell lung cancer (for example, lung adenocarcinoma).

Abstract: The present invention relates to a chemical coupling linker and use thereof, and a bioactive conjugate prepared by the chemical coupling linker. The present invention also relates to use of the bioactive conjugate in the preparation of a drug for the prevention or treatment of tumor diseases.

Abstract: A dynamic loose vehicle formation method based on real-time online navigation map, which belongs to the field of vehicle formation technologies. The method includes a driver inputs travel information of a destination and waypoints in a GIS app; the GIS app uploads the travel information to a GIS server; the driver chooses to join a recommended formation or create a formation in the GIS app; when the driver chooses the formation and joins the formation, the formation information is displayed on the GIS app interface and sent to other vehicles within the formation for information interaction; when the driver chooses to leave the formation and leaves the formation, the formation is adjusted and the GIS server updates the formation information.
