| 摘 要： | 介绍了地壳垂直运动的均衡理论 ,基于全球通量均衡基准 ,建立了任意坐标系下描述地壳垂直运动的动力学模型。该模型可表述为 L aplace方程的第二边值问题。将此模型与调和分析模型做了比较 ,认为此模型拟合精度较高 ,理论上更严密

| Abstract: | The isostatic theory of crust vertical movement is introduced.On the basis of the flux isostatic datum,a dynamical model,by which the crust vertical movement can be described is established.This model can be described as a Laplace equation with the second boundary condition.As comparing this model with harmonic analysis model,it is indicatied that this model is better and more rigorous in theory. |
