Abstract: A radiographic inspection device and a method of inspecting an object are provided. The radiographic inspection device includes a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has a first opening connecting to an outside; a transfer mechanism applicable to carry the object to move through the inspection space; a shielding curtain mounted at the first opening; and a driving mechanism mounted on the support frame and configured to drive the shielding curtain to move, so as to open or close the first opening. Since the driving mechanism drives the shielding curtain to rise or fall, it is possible to ensure that the lightweight object for inspection may smoothly enter the inspection space for subsequent radiographic scanning.

Abstract: A whole-vehicle-based method for evaluating extreme pressure and antiwear properties of grease includes injecting the grease onto a key bearing pin and causing the engineering machine to operate without load is disclosed. The method includes causing the engineering machine to operate under a load of 10% to 150% rated load at least once, viewing and analyzing a wear condition of a surface of the bearing pin, and issuing a whole-vehicle-based evaluation report of extreme pressure and antiwear properties of grease. The engineering machine is caused to operate once under a load of 10% to 150% rated load for 0.5 min to 100 h.

Abstract: This application provides a switch assembly and a vehicle.

Abstract: Disclosed is a method for fabricating a wearable hydrogel glucose sensor, belonging to the technical field of biomedical sensing, including using polyacrylamide hydrogel as a basic material, preparing a hydrogel film by adding with phenylboronic acid group capable of recognizing glucose molecules, and carrying out grating writing on the hydrogel film in a femtosecond laser direct writing mode to obtain the wearable hydrogel glucose sensor. The hydrogel film combines with glucose and expands linearly, which makes the grating period and effective refractive index change. The quantitative measurement of glucose is realized by detecting the spatial position of diffraction band and the change of diffraction power intensity.
