中文摘要：

在欧空局提供的FLUMIC模型的基础上，加入了地球同步轨道GOES卫星在2003--2009年大于2MeV的高能电子通量数据，验证改进了其在L=6．6Re处的理论公式；并利用FLUMIC模型在一般L值情形下的理论公式，设计编写了航天器内部充电评估软件。此软件能计算在一定的时间内，卫星在轨运行时可能遭受的粒子微分通量或积分通量值，以作为航天器高能辐射防护的设计依据。

英文摘要：

Based on the FLUMIC model of ESA, we use the energetic electron （〉2 MeV） flux data of geosynchronous GOES satellites during 2003--2009 to evaluate and improve the flux distribution formula of FLUMIC at 6.6 Re. We further design and develop a set of spacecraft internal charging evaluation software using the formula of flux distribution versus L-shell from FLUMIC. This software can calculate the electron differential flux or integration flux environment of the satellites with its time and orbit parameters as input and provide useful information for the design of spacecraft＇ s high energy particle protection part.
