LLR法检测月球自由天平动的原理

Principle of the Determination of the Free Librations of the Moon by Means of the LLR Method

本文在视月球自由天平动为受迫天平动的附加运动之物理思想前提下,借助于雅可比行列式变换的数学手段,具体推导了激光测月理论时延τ。对月球自由天平动参数的偏导数,从而给出LLR法检测月球自由天平动的原理。

In this paper, under the physicallidea that the tree librations of the Moon are taken to be the additional oscillations of the forced librationr, the partial derivatives of the time delay τc in the theory of lunar laser ranging with respect to the parameters of the free librations by means of the mathematical means of the transformation of Jacobian, thereby giving the principle of the determination of the free librations of the Moon according to the LLR method.
