摘　　要：以均匀覆盖层中氡迁移方程为基础,推导了二维有限差分法的数值模拟方程。提出了用VB和Matlab混合编程实现数值模拟可视化系统的总体设计。详细叙述了混合编程和迭代法求解差分方程的实现方法。为研究均匀覆盖层中氡迁移的研究者提供一个实用的研究工具,同时也为其他研究人员开发相关系统探索了一种较为便捷的开发途径。On the grounds of the radon transport equation in the even overburden layer, the value simulation equation using the two-dimensional finite difference method had been infered, and the visible system of value simulation was proposed by programming with VB and Matlab. The mixed programming and the method of using repetitive process to solve difference equation were narrated in detail. Through this paper, a practical tool was offered to the researcher studing on the radon migration in the even overburden layer, and a more convenient developing way was explored for the researchers developing the relative system.
