利用重力/地形导纳和岩石圈单一薄层模型的月球物理参数反演

针对月震数据分布不均，传统反演方法不易搜索全局最优解等问题，提出联合使用重力/地形导纳和非线性粒子群PSO算法同时反演月球物理参数的方法。结果表明，该方法构建的表面地形载荷模型和内部异常密度载荷模型合理，粒子群PSO算法能同时求解月球物理参数及其全局最优解.将方法运用于月球物理参数的反演，可为月球内部结构研究提供一定的参考。

Application of Gravity/Topography Admittance to the Inversion of Lunar Geophysical Parameters Considering the Lithosphere as a Thin Elastic Spherical Shell

Because of the Apollo lunar seismic network merely located on the near side of the Moon and the traditional methods failing in the best solutions，several lunar parameters such as load ratio f，crustal thickness bc，subsurface load depth Zb，crustal density pc，lithospheric elastic thickness Te can be solved through lunar gravity/topography admittance with PSO. Results indicate that surface and subsurface load models are rational and all the best solutions of the lunar parameters studied can be simultaneously calculated. It can provide a reference for lunar internal structure research，when such method investigated here applied to lunar geophysical parameters inversion.
