【摘要】：对月球上的月尘静电浮扬现象进行了理论研究,对比分析了影响月球表面静电浮扬强弱的主要因素.研究过程分为两个步骤:首先采用一维PIC(particle in cell)模拟计算了月尘和月球表面的充电过程,然后基于这一结果引进试验粒子,对月尘的静电浮扬现象进行了分析研究.结果表明月尘的静电浮扬主要受两个因素的影响:太阳角和月尘颗粒的大小.月尘静电浮扬现象在日出日落时分更容易发生,即太阳角越小越容易引起剧烈的月尘浮扬现象;并且月尘粒径越小,其浮扬高度越高.
[Abstract]:In this paper, a theoretical study on the electrostatic floating of the lunar dust on the moon is carried out, and the main factors that influence the static uplift of the surface of the moon are compared and analyzed. The research process is divided into two steps: firstly, the charging process of the lunar surface and the lunar surface is simulated by using a one-dimensional PIC (particle in cell), and then the test particles are introduced based on the result, and the static floating phenomenon of the lunar dust is analyzed and studied. The results show that the electrostatic floating of the dust is mainly influenced by two factors: the sun angle and the moon dust particle size. The monthly dust electrostatic floating phenomenon is more likely to occur at the time of sunset and sunset, that is, the smaller the sun angle, the more likely to cause a violent monthly dust float phenomenon; and the smaller the monthly dust particle size, the higher the flying height.
