摘　　要：通过建立多电子枪模拟空间能谱等离子体环境的试验方法,完成了单麦克斯韦和双麦克斯韦等离子体环境下,Kapton材料和太阳电池玻璃盖片表面电位测试试验。研究表明,试验结果和NASCAP/GEO软件计算结果一致性较好,验证了采用多电子枪模拟空间能谱等离子体环境试验方法的有效性和准确性。mA method of simulating the distributed spectra of space plasma is developed by multi-monoenergetic electron beams. And the surface charging potentials of Kapton material and the cover glass of solar arrays are measured under the single Maxwellian or bi-Maxwellian distribution plasma environment. It shows that the measured results are in good agreement with that calculated by NASCAP/GEO software, and indicates that the simulated method is effective and accurate.
