摘要
从月球的自由天平动,引力场和耗散等可以研究月球内部的结构和演化.本文从理论上估计了用激光测月资料推算月球自由天平动的精确度,根据四个激光测月台站的18年的观测资料计算了月球自由天平动的振幅和相位、月球转动惯量等,并初步得到了月球的内部结构和组成成分.
Information about the structure of lunar interior and evolution could be obtained from measurements of lunar free librations, gravitational field, dissipation etc. In this paper the precisions of determining free librations with the lunar laser ranging data are estimated. Using the observing data from four stations for eighteen years the amplitudes and phases of free librations, moments of inertia etc. were obtained.
