高斯扩散模式适用于均一的大气条件，以及地面开阔平坦的地区，点源的扩散模式。排放大量污染物的烟囱、放散管、通风口等，虽然其大小不一，但是只要不是讨论烟囱底部很近距离的污染问题，均可视其为点源。(The Gauss diffusion model is applied to homogeneous atmospheric conditions, as well as to ground open flat regions, and to point source diffusion patterns

参考各种文献以及实验条件，得到微晶片激光器的各物理参数，在matlab中编程求解该微晶片激光器对应的速率方程组。(Referring to various literatures and experimental conditions, we get the physical parameters of the microchip laser, and solve the rate equations of the microchip laser in MATLAB.)

能够计算不同排列情况下的能带结构，只需更给晶格常数，选择排列方式以及介电常数即可(It is possible to calculate the energy band structure under different arrangement conditions, only by giving lattice constants, arranging permutations and permittivity.)
