中文摘要：
基于SGM100i和最新月球重力场模型GLGM-3比较,分析了月球自由空气重力异常和月球大地水准面起伏。利用SGM100i绘制了月球垂线偏差及其分量的全月分布图,并分析了垂线偏差与月球地形特征、质量分布之间的相关性,发现利用垂线偏差反演得到的月球地形、质量分布均与实际情况一致。
英文摘要：
Lunar gravity field plays a key role of researching the interior structure of the Moon.SGM100i can well reveal the lunar characters in a global sense owing to the SELENE data.In this research,comparison has been made between SGM100i and the latest model GLGM-3 in aspects like free-air gravity anomalies and selenoid undulations.The distribution of deflections of the vertical（DOV） and their components have also been shown,and relations between the DOV and lunar terrain and mass distribution have been analyzed.The lunar terrain features and mass distribution recovered from there quantities are consistent with the facts,which means DOV and its components should be used in revealing lunar features as well.
