中文摘要:
      目的 研究月球表面不同等离子体环境下航天器表面充放电效应情况。方法 利用欧空局开发的SPIS软件建模,并仿真模拟,通过分析表面电流种类、大小,得出不同环境下的一般性的充放电规律。结果 月球表面探测器存在表面充电风险,磁鞘层、磁尾瓣、等离子体片及太阳风4种不同典型等离子体环境下表面充电电位差异较大,连接处充电电位存在分布不均匀的渐变现象。表面充电电位区间约为-1784~142 V。结论 光照条件能显著影响探测器表面电位,特殊区域充电电位会受到临近区域充放电效应形成的新的小范围等离子体环境的影响。
英文摘要:
      The paper aims to study the situation of spacecraft surface charging and discharging under different plasma environments on the lunar surface. The SPIS software developed by ESA was used to model and simulate. By analyzing the types and sizes of surface currents, the general charging and discharging laws in different environments were obtained. There was a risk of surface charging for the lunar surface probe. The surface charging potentials of the magnetic sheath, magnetic tail lobe, plasma sheet and solar wind were significantly different under four different typical plasma environments, and the charging potentials at the junction were gradually changed with uneven distribution. The surface charging potential range was about -1784 to142 V. Illumination conditions can significantly affect the surface potential of the detector, and the charging potential in special areas will be affected by the new small-scale plasma environment formed by charging and discharging effects in adjacent areas.
