【摘要】：對月球上的月塵靜電浮揚現(xiàn)象進行了理論研究,對比分析了影響月球表面靜電浮揚強弱的主要因素.研究過程分為兩個步驟:首先采用一維PIC(particle in cell)模擬計算了月塵和月球表面的充電過程,然后基于這一結(jié)果引進試驗粒子,對月塵的靜電浮揚現(xiàn)象進行了分析研究.結(jié)果表明月塵的靜電浮揚主要受兩個因素的影響:太陽角和月塵顆粒的大小.月塵靜電浮揚現(xiàn)象在日出日落時分更容易發(fā)生,即太陽角越小越容易引起劇烈的月塵浮揚現(xiàn)象;并且月塵粒徑越小,其浮揚高度越高.
[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.
