【摘要】 给出了守恒型模型方程的差分型格子气方法，通过定义广义的分布函数，将原方程的求解问题转化成关于分布函数的差分算法。该方法的意义在于建立格子气方法与差分法之间的联系，进而可以构造真正用于空气动力学的格子气模型，使格子气方法在可压缩流领域成为一种实用方法。分别构造了两步ＭａｃＣｏｒｍａｒｋ格式和ＷａｒｍｉｎｇＢｅａｍ格式的分布函数的差分方程更多还原

【Abstract】 A Lattice Gas Method has been used for conservation equation in a model equation by defined general distribution function. The model became a bridge between Lattice Gas Method and Finite Difference Method. It is shown that the method is effective by simulating model equation with MacCormark and Warming Beam schemes.更多还原
