    with the development of the automobile industry, more and more general electrical parts are used in automobiles, and the quality of platform and standardized electrical products is also paid more and more attention. Relay plays an important role in auto regulation, safety protection and conversion circuit, so it is widely used in the whole vehicle.Over travel is one of the important parameters of automobile relay, and its consistency affects the life of relay and other main performance. In traditional manual assembly production or semi-automatic assembly line, due to the inherent errors in parts and assembly, a large number of manual adjustment relays are often needed to over travel

    The study of high-order harmonic generation (HHG) in confined quantum systems is essential for developing a comprehensive physical description of harmonic generation from atoms to bulk solids. Using the time-dependent density-functional theory, we demonstrate how the symmetry of the system modulates the generation of high-order harmonic in fullerene C60 molecules along different orthogonal directions, as well as the effects of amplitude and photon energy of a linearly polarized laser on high-order harmonics generation. We found that the generation of high-order harmonics perpendicular to the laser polarization direction (LPD) is related to the symmetry of molecules along the LPD and the symmetry of molecules perpendicular to the LPD. Within a certain parameter range, the cut-off energy is linearly proportional to the laser amplitude and the laser photon energy
