本程序是使用MATLAB语言采用迎风格式解对流方程，对流方程在工程上有很广泛的应用，而迎风格式的精度比较高还包括用跳点格式解扩散方程的初值问题，所以有两个程序 (This procedure is to use the MATLAB language solution using upwind convection equation, the convection equations in engineering, there is a wide range of applications, and the accuracy of upwind scheme also includes a relatively high point format with jump-diffusion equation solution of the initial value problem, so there are two procedures)

说明：  可计算地下洞室的围岩稳定问题，模拟地下洞室的开挖、支护过程，介质可以是均质体，也可以是分区变化的非均质体，还可有夹层、节理等。(Calculate the stability of underground rock caverns, underground excavation simulation, supporting the process, the media can be a homogeneous body, you can also change the partition of non-homogeneous body, but also as a layer, joints and so on.)
