| 摘 要： | 本文根据地壳运动的全球通量均衡假说建立了地壳垂直形变场的分析模型,分析了以往作者所研究的球谐函数和球冠谐函数模型的优缺点,着重推导了在密切平面坐标系下该模型的Fourier级数解,该模型一方面可以简单地应用于地壳垂直形变场的逼近,另一方面为采用谱分析法提取地壳垂直形变场信息提供了理论依据。

| Abstract: | Based on the hypothesis of the global flux isostatic datum, in this paper, the analysis model of crustal vertical movement has been established. The spherical harmonic model and spherical cap harmonic model have been deduced and their advantages and disadvantages have been analyzed. Besides, the Fourier analysis model based on the plane coordinates has been proposed which is better for being simply used on analyzing the mechanism of deformation field of the crustal vertical movement. |
