查询词典 RMS

With the new lunar gravity models LP165P and GLGM2,we analyze the character of the lunar gravity field,compute corresponding degreewise rms, and give gravity anomaly distribution figures at different height of the two models. Then we analyze and compare the character and difference of the lunar gravity models truncating to different orders and degrees at different height.
