摘要
基于地壳垂直运动的均衡理论,讨论了球谐函数法用于区域地壳垂直形变场逼近时所存在的问题,提出并推导了球冠谐分析法逼近区域地壳垂直形变场的模型。并利用该模型对两个实际区域进行了试验,取得了良好的效果。
Based on the isostatic theory of crust vertical movements and considering some unavoidable defects in crust vertical deformation fitting by use of spherical harmonic method, puts forward the spherical cap harmonic analysis method, and derives a corresponding model for approximating to regional crust vertical deformation. In the end, two tests have been done in a regional area and some useful conclusions have been drawn.
