The Poisson integral is usually used to transfer gravity from the topographic surface to the geoid in a so called downward continuation of gravity.
泊松积分通常用于把重力值从地球表面转化到大地水准面 (即称之为重力向下延拓 )的过程中。
By using the connections between a 2 - D Brown Motion and the harmonic equation, some of the properties for Brown Motion and Poisson integral formula we provide a probabilistic numerical solution for the harmonic e-quation.
利用二维布朗运动与调和方程之间的联系,以及布朗运动一些特有的性质和圆上的泊松积分公式,给出了调和方程的一个概率数值解法。
