目前三维的混凝土建模很少见，随机球形骨料在受限空间（球体）随机分布模型,本人自己编写，具有原创性。动画显示建模过程。三种粒径不同的骨料随机分布。模拟混凝土材料的过程。有助于后续有限元计算。(Random spherical aggregate in the restricted space (sphere) random distribution model, I write it myself, with originality. Animation shows the modeling pr

Matlab模拟多光束干涉光场分布，文件内包含计算所得的两束，三束，四束光干涉的光场分布。程序内可任意改变光束参数(this part of matlab code is used to stimulate the distribution of the strength of the multi-beam interference)
