摘　　要：在考虑羽流主要成分在不同温度固体表面吸附时间的基础上,给出了在轨太阳帆板温度的计算模型,综合考虑硅片透射率衰减和温度升高因素,建立了太阳帆板功率损失的计算模型。基于主要羽流污染物一甲基肼(MMH)-HNO3的透射率试验数据,推导出功率总损失计算模型。某地球同步卫星太阳帆板功率损失的计算结果表明:当污染层厚度达3.3×10-3g/cm2时,太阳帆板输出功率下降程度不可忽视。The temperature calculation model of on-board solar array was given out based on the consideration of residence time on the solid surface for the major components of plume under different temperature in this paper.The mathematic expression of solar array power loss was established when the two factors that were the transmissivity attenuation of silicon sheet and the temperature raising were considered simultaneously.Based on the test data of the transmissivity for monomethylhydrazine nitrate which was the k...
