spherical harmonic analysis meaning in English

球面谐波分析

In view of the limitation of the traditional inversion theory and method of the gravity and magnetic field , professional an yulin , etc , worked in china university of geoscience , has come into being the theory system of the all - direction imagery for local gravity and magnetic sources after having researched a few years . the theory system broke through the thinking method of traditional theory system , researched all - direction imagery of the 2d local gravity and magnetic sources by means of complex function theory and researched all - direction imagery of the 3d local gravity and magnetic sources by means of spherical harmonic analysis theory , developed greatly the interpretation theory on the gravity and magnetic field
该理论体系突破了传统的重、磁场解释理论体系的思维方式，采用复变函数理论研究二维局部重磁场源全方位成像，采用球谐分析理论研究三维局部重磁场源全方位成像，大大发展了重磁学科解释理论，可以在起伏地形、有背景叠加和高频干扰等复杂条件下，直接反演加叠代修改，求解分布在有限范围内的二维和三维重磁场源异常场的多种反演问题。
