某扫描仪辐射发射超标解决及验证方案（英文）

The problem of excessive radiated emission for a certain type of laser scanner is discussed in this paper. Firstly, the frequency characteristics of the laser scanner can be obtained by traditional test methods. According to the frequency and electronic equipment characteristics, the interference source can be estimated and established. Then based upon analysis, modified methods are proposed. By applying the above methods, the interference source can be identified and the amount of radiated emission from the scanner can be reduced effectively. Finally, the scanner can operate in a compatible manner with other electronic systems at the same time. The above methods can provide a reference for electronic equipment design ensuring electromagnetic compatibility and passing the radiated emission test.

长征八号运载火箭减载效果评估及验证（英文）

LM-8 inherited mature modules from other launch vehicles, adapting the overall design through the combination of engine throttling, wind compensation and load relief control, so as to reduce the aerodynamic load during flight. This paper proposes a rapid evaluation method for load relief performance, which takes launch vehicle's characteristics, wind field, control parameters, aerodynamic deviation and structure deviation into consideration, and provides a quick estimation method for load relief performance. The load relief performance of the LM-8 launch vehicle estimated by this method achieved 10%-20% in pitch and 20%-40% in yaw. The specific results are related to parameter deviation, the altitude of wind shear and the relationship between wind direction and trajectory angle. Simulation results for a typical case with six degrees of dynamic freedom of flight proves that the comprehensive load relief performance would be between 14% to 34%, which is in line with the aforementioned method. In addition, simulation results indicate that the more severe the wind shear is, the better performance of load relief can be achieved.
