A scanning electron microscope according to the present invention enables a shaft to be detached from a sample installation unit, thereby addressing issues related to the shaft, such as simple calibration related to the shaft, misalignment of a beam speed, replacement of consumables, etc., by replacing the entire shaft. As such, the scanning electron microscope has the advantage of being simply and easily repaired and maintained.

The invention relates to the electromechanical field, and discloses a tractor and automobile chassis load running-in test bench and a running-in process thereof, wherein the running-in test bench includes an input mechanism, a lifting mechanism, an output mechanism, a loading mechanism, a base, a hydraulic purification system and an automatic control system; The input mechanism is located at one end of the base, and a lifting mechanism is arranged between the input mechanism and the base; the output mechanism and the loading mechanism are located at the other end of the base, and the loading mechanism is located below the output mechanism and passes through the coupling and the output mechanism connection; the automatic control system is electrically connected with the input mechanism and the loading mechanism; during the running-in test, the input mechanism, the output mechanism and the hydraulic purification system are respectively connected with the tractor or the automobile chassis test piece. The running-in process mainly adopts the loading and running-in purification process. The invention has the beneficial effects of improving the quality of the whole vehicle, saving energy, time, occupying space, improving production efficiency, reducing the repair rate of products leaving the factory, and being capable of automatic control.

The invention discloses a layout design rule detection file verification graphics library and an establishment method thereof. The layout design rule check file verification graphics library comprises a minimum line width, a minimum space, a minimum distance enclosing another graphic layer by one graphic layer, a minimum distance extending to another graphic layer from one graphic layer, a single-layer graph with the minimum width overlapped by two graphic layer parts, and design rule check among multilayer graphs. According to the layout design rule detection file verification graphics library provided by the invention, on one hand, the incomplete verification graph kinds due to inadequate experience of a verification engineer can be made up; on the other hand, the development cycle of establishing the verification graph can be shortened. The layout design rule detection file verification graphics library can be used for providing the reference for manually establishing the verification graphs by any layout verification engineer and can also be used for an automatic generation tool of the verification graph, directly calling a graphics library file and realizing batch production of the verification graph by using a tool to modify the basic line width, the layer and other variables.
