| 摘 要： | 分子污染是引起卫星太阳电池翼输出功率衰减的因素之一。用直接模拟蒙特卡罗（Direct Simulation Monte Carlo）方法分析了空间分子污染物的传输过程，采用十组不同的输入参数计算了在轨运行期间分子污染物在某型号卫星太阳电池翼表面的沉积膜厚度，分析了太阳电池翼输出功率的衰减情况。

| Abstract: | Molecular contamination is one of the factors which make the solar cell output decrease. This paper analyses the molecular contaminant transport process using Direct Simulation Monte Carlo method. The thickness of molecular film on the satellite solar cell, as well as the attenuation of the solar cell output power output during orbital operation, are given, through ten different input data to simulate the total process of molecular contamination. |

| Keywords: | Molecular contamination modeling Direct simulation monte carlo Power output Attenuation |
