摘要
该文探讨和介绍了地下水运动中几类常用的随机微分方程模型与求解方法。如带有随机边界条件、随机力函数及含有随机系数的地下水运动模型；并将多孔介质中地下水运移近似看作布朗运动，引入伊藤随机积分研究地下水运动规律。
This paper discusses and introduces several kinds of commonly used model of stochastic differential equation and the method of solution in the groundwater movement. For instance, the groundwater movement models with stochastic boundary conditions, with stochastic force functions and containing stochastic coefficients. Also, approximately viewing the groundwater migration in porous media as Brown movement, the laws of groundwater movement being studied by introducing Ito stochastic integral.
