摘要
月球地形、重力场和内部构造不仅对于研究月球起源和发展具有重要意义,而且对月球探测器轨道的飞行控制、月球着陆器的着陆区选择也有重要的影响.本文首先回顾了月球地形观测的方法和模型,并对新近"嫦娥一号"和"Kaguya/Selene"得到的地形模型做了分析和比较.其次,讨论了新近月球重力场研究的现状,并给出了综合新近及既往数据解算重力场的方法.最后,分析了综合地形和重力场,并给出利用新近数据研究月球内部构造的进展.
The Lunar topography model, gravity field and internal structure have great significance not only to the study of the lunar origin, but also to probing the Lunar orbit flight control and lunar lander landing zone selection. This paper reviews the lunar topography observation methods and models, and then the newly obtained Kaguya/ Selene and Change E-1 topography model were analyzed and compared. Secondly the research status of the new lunar gravity field is discussed and method of calculating gravity field is studied using integrated new and previous data. Finally, the research progress of the lunar internal structure is analyzed based on the topography and gravity field.
