蒙特卡罗方法生成二维麦克斯韦分布的程序在一些计算物理教材中已经做出.将三维单位球面上均匀分布的随机 向量加入到描述分子碰撞的随机过程中，用MATLAB 生成了三维麦克斯韦分布的程序.并对麦克斯韦分布的数值结果与理论 预期进行了对比.对应地提出了一种理想气体碰撞生成麦克斯韦分布的在统计上所可能遵循的散射规律.

Generating two-dimensional Maxwell distribution using Monte Carlo method has already been presented in some numeric textbooks.Putting three-dimensional spherical surface random vectors in the process that representing the collision between molecules three-dimensional Maxwell distribution can thus form.The corresponding code is in MATLAB language and the comparison between the numerical result and the theoretical expectation is made.
