摘      要：electronic devices and magnetic sensors. In particular, the application of these technologies in the aerospace field has been favored by researchers, such as the development of a new Hall thruster as a plasma optical device and its application in space thrusters, and the use of molecular dynamics software to calculate the degradation of atomic oxygen on the surface of the spacecraft and polymer materials, which affects the life of the spacecraft. Through the surface plasmon resonance effect of noble metals including Au, Ag or other metals, many excellent optical devices, especially biosensors, can be designed for the detection of glucose. It is worth noting that the problem of photocatalysis technology is still to find excellent photocatalysts to efficiently degrade pollutants. [1] The construction of heterojunction has become a key technical means to solve the problem of photocatalyst synthesis in the current environmental purification *** this volume, the Particle-in-cell model is used to simulate the design of a 5 kW Hall thruster that will be used for space propulsion. Simultaneously, the influence of magnetic field on the performance of Hall thrusters is studied. There is a large amount of atomic oxygen in low Earth orbit, and these atomic oxygen will cause great corrosion to the spacecraft surface and affect the life of the spacecraft. The life of a spacecraft can be effectively simulated by using molecular dynamics model on the impact of atomic oxygen on the polymer material on the spacecraft surface.
