摘要： The present disclosure provides a numerical simulation method of pulsed laser paint removal and a use thereof. This method establishes a three-dimensional (3D) temperature field model by ANSYS software to perform a numerical simulation of nanosecond pulsed laser paint removal. A high-speed moving pulsed laser is loaded on a surface of the model in a form of heat flux, and a coordinate system is moved to realize loading on different paths. A special surface mesh screening method is used to realize loading on any surface, and it ensures that laser energy distribution on a material surface is in line with reality. In addition, an element birth/death technology is combined to remove an element that exceeds a threshold, so as to intuitively present the surface morphology after laser paint removal. The present disclosure can realize the prediction of the contour of a paint layer ablated by a pulsed laser.

摘要： Disclosed are a baffled integrated denitrifying and decarbonizing device with anaerobic bio-nests and a baffled integrated denitrifying and decarbonizing process with anaerobic bio-nests thereof. The wastewater with low carbon-nitrogen ratio first enters anaerobic chamber I, then enters anaerobic chamber II and chamber III to complete anaerobic decarbonization and denitrification. The chambers are provided with modified basalt fiber carrier media to enrich a large number of functional microorganisms, and improve the device in terms of anaerobic treatment efficiency. Fermentation liquid in chamber III then flows back to aerobic chamber IV to complete the nitrification process. Nitrified liquid enters chamber I and mixes with influent for further treatment, and effluent is finally discharged from chamber III. The clapboard and basalt fiber felt in chamber IV can retain and enrich autotrophic/heterotrophic nitrifying bacteria.

摘要： A control method for hybrid electromagnetic suspension. The method provides four modes for hybrid electromagnetic suspension: a comfort mode, a sport mode, a combined mode, and an energy feedback mode. A driver can switch between the four modes as desired. For the comfort, sport, and combined modes, hybrid control is adopted, and two sub-modes are provided: an active control mode and a semi-active control mode. A switching condition between the two sub-modes is determined by using a novel parameter Cact and comparing the same against a maximum equivalent electromagnetic damping coefficient Ceqmax of a linear motor. The present invention solves the problem of achieving a balance between suspension comfort and tire traction, and meets the demands of different operating conditions and users by enabling manual mode switching. In addition, the hybrid control is employed to solve the problems of high energy consumption of active suspension and limited control performance of semi-active suspension, thus ensuring good kinematic performance of automobile suspension while reducing energy consumption. Furthermore, the energy feedback mode is designed to enable the suspension to perform energy recovery, meeting demands of energy conservation and emission reduction.

摘要： A non-linear optical pumping detection apparatus and a non-linear optical absorption cross-section measurement method, which can simultaneously measure degenerate and non-degenerate two-photon absorption cross-section spectra. The measurement process is automatic, efficient and fast. The working wavelength band is from 380 nm to near infrared 1064 nm, and the non-linear performance measurement of the super-continuous wide spectra can be realized. A zoom optical system with a larger entrance pupil diameter is adopted as a weak signal acquisition lens. So the weak signal can be effectively extracted from background noise. Meanwhile, the mean square root diameter of an on-axis image point of the zoom optical system is 100 to 150 microns, the divergence angle 2α of the on-axis image point is 30.6 degrees, which well match the optical fiber coupling condition, thereby improving the coupling efficiency of the space light coupling into the optical fiber, and greatly improving the measurement sensitivity.
