摘要: 针对月震数据的局限性,以及传统反演方法求解月球物理参数的不适宜性,利用非线性粒子群PSO算法同时求解岩石圈主要月球物理参数载荷比、月壳厚度、月壳密度、内部载荷深度、岩石圈弹性厚度等.结果表明:粒子群PSO算法能够同时反演多个月球物理参数的最优解,计算效率高于传统方法.将该方法应用于月球物理参数多参数的反演,可为月球内部精细结构研究提供参考.

Abstract: With application of particle swarm optimization to lunar geophysical parameters inversion, problems resulted from limitation of lunar seismic network and/or unsuitability of conventional inversion methods are avoided. Parameters investigated include load ratio, crustal thickness, crustal density, subsurface load depth and lithospheric elastic thickness. It indicates that the approach is able to calculate model parameters best fitting observed ones automatically and simultaneously. It performs better in computational speed. It is therefore quite useful in lunar multi-parameters inversion and can be employed in lunar interior precision structure research.
