| 摘 要： | 本文将小波多尺度分析引入月球重力场的研究,选取测量数据质量较好的月球近区作为实验区域,以“Clementine”探测器获得的自由空气重力异常作为原始数据对主要月海盆地进行了局部的重力异常分解,解释了月球内部基本分层结构,并利用主要月海盆地的实验结果分析了月海下部质量异常以及莫霍面的起伏形态,与已有研究成果进行比较证明了方法的适用性及结果的合理性.

| Abstract: | Wavelet multi-scale analysis is applied to the research on lunar gravity field and the explanation of lunar inner structure. In this paper, the nearside of the Moon with higher quality data is chosen as the test area, and free air gravity data from "Clementine" mission are used as original data to decompose gravity of some specific mare basins. With the results of numerical test, we also explain the hierarchical structure of the Moon, analyze the thickness of mare fillings and the Moho topography under mare basins, and verify the results by comparisons. |
