高能(350KeV)-中能(18—30KeV可调)-低能(4—5KeV可调)电子联合辐照聚酯薄膜和特氟隆薄膜,得到与中能电子辐照、高-中能电子联合辐照以及中-低能电子联合辐照不同的结果。实验结果表明,高能电子能诱发电介质薄膜充放电。特氟隆薄膜的三能电子联合辐照实验结果与Coakley和Treadaway的1-100keVdN/dE∝E~(-2)谱电子辐照实验结果以及NASCAP计算机模拟结果符合。得出结论,三能电子联合辐照可较为完善地模拟静止卫星电介质的充放电效应。论证了选用三种能量电子的充分性和必要性。推断出,如果在星食期遇到象1979年4月24日磁层亚暴事件,则静止卫星表面某些电介质局部电位有可能超过SCATHA卫星近期数据给出的和NASCAP计算的-2—-4KV,而且会出现大的放电。
High Energy (350KeV) - Medium Energy (18-30KeV Adjustable) - Low Energy (4-5KeV Adjustable) Electronical Combination of Irradiated Mylar and Teflon Films to Achieve Electron-Irradiation with High- Irradiation as well as different results for combined medium- and low-energy electron irradiation. Experimental results show that high-energy electrons can induce charge and discharge of the dielectric film. The experimental results of tehne-electron combination irradiation on Teflon film coincide with those of Cokeley and Treadaway’s 1-100 keVdN / dEαE ~ (-2) spectra and the NASCAP computer simulation results. It is concluded that the combination of three electrons can simulate the charging and discharging effects of the geostationary satellite dielectric perfectly. Demonstrated the adequacy and necessity of selecting three kinds of energy electrons. It is inferred that if during the asteroid encounter a stratospheric storms event such as April 24, 1979, some of the dielectric local potentials on the surface of a stationary satellite are likely to exceed the -2-2, calculated by the recent data from the SCATHA satellite and calculated by NASCAP, 4KV, and there will be a big discharge.
