摘要
以扩散、渗流理论为基础，借助传热学、传质学中的基本理论，对瓦斯的解吸过程进行理论推导，建立了瓦斯扩散—渗流方程，并采用隐式差分法对瓦斯一维平行流动和径向流动方程进行了计算机模拟，结果与生产现场较为相符。
Based on the theory of diffusion and permeation,the equation of diffusion with the aid of the basic theory of science of heat and quality is derived.Using implicit difference method ,the equation of onedemension parallel and radial flow is simulated by computer.
