摘要:
着重于寻找月核证据并将月核模型引入月球天平动理论中,探讨如何将多种空间探测技术应用于毫 角秒精度的月球天平动观测,进而测定液态和固态月核参量。通过讨论多层月球的月球物理参数、流体核的几何与动力学椭率、松散黏滞的月幔,可获得月球相关详细信息与参量,这些参量对评估多层结构的月球自由天平动很重要。物理天平动的解析理论还可应用于未来多种月球工作中,期望在近代月球科学研究基础上能有进一步发展。

Abstract:
The emphasis will be put on the evidences of lunar core existence and on the necessity to take this fact into account in the lunar librations theory. Our goal is to show how the millisecond precision observations of lunar physical librations in the projects. We discuss geophysical parameters, geometrical and dynamic ellipticity of liquid core and viscose-elastic mantel of the multilayered Moon. The research results include the survey of internal structure of the Moon, tabulated values of geophysical parameters and geophysical profile of the Moon, including liquid lunar core, values of geometrical compression on the Moon’s surface, densities, as well as graphic representations of the received data. The new prospects for horizons of research and development of the Moon for the nearest decade will be opened.
Key words:  Moon; interior; dynamics; physical libration; lunar missions
