Abstract: The present invention provides a nanolayer-lubricated diamond grinding wheel grinding method based on a shock wave cavitation effect. In the method, after a gas pressure regulation valve is turned on, a shock wave generated by an acceleration tube pushes nanoparticles to move forward, and the nanoparticles are then accelerated by a small de Laval nozzle to acquire a high initial velocity. One wave source of a shock wave speed-increase module generates a high-frequency high-strength shock wave, to impact nanoparticles with an initial velocity, to enable the nanoparticles to be continuously accelerated downward in an axial direction of a large de Laval nozzle, until the nanoparticles are embedded on a grinding wheel surface at a maximum speed to form a nanolayer. The other wave source is used to clean impurities on the grinding wheel surface.

Abstract: A device and a method for detecting cigarette fly ash by a gray-scale difference based on machine vision (MV) are provided. A manipulator holds a cigarette as a detection sample to simulate a human smoking action, and multiple groups of cameras track a simulated smoking process of the detection sample synchronously in real time. It is determined whether fly ash appears based on a gray-scale difference of burning ash columns, produced without being subjected to flicking, in acquired images. A fly ash area of the burning ash columns of the cigarette is calculated by an area with the gray-scale difference of the burning ash columns of the cigarette in two sequential images of the burning ash columns of the cigarette, and a fly ash amount is further determined. The detection of the amount of fine fly ash is converted into the detection of the gray-scale difference.
