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. Chimneys, pipes, vents, etc. that emit large quantities of pollutants, although they vary in size, can be regarded as point sources as long as they do not discuss the pollution problems near the bottom of the chimney.)

说明：  超短脉冲是谐振腔中增益与损耗达到平衡、色散与非线性达到平衡时所产生的。本模拟是采用分步傅里叶的解，数值求解薛定谔方程。求光孤子在光线内传输。(Ultra-short pulses are generated when the gain and loss of the cavity are balanced, and the dispersion and nonlinearity are balanced. This simulation uses a stepwise Fourier solution to numerically solve the Schrodinger equation. Find the optical soliton to propagate in the light.)

平面波从空气入射到石英玻璃中的P、S分量的能流反射率和透射率(Energy flow reflectivity and transmissivity of plane wave from P to S in the quartz glass.)

matlab语言编写，适合图形文章数据提取(Matlab language, suitable for data extraction of graphic articles)

For the model of indoor air distribution tuyere proposed by Professor Zhang Tengfei, this paper is UDF code for fluent simulation.

一维和二维Airy光场的输出，以及不同距离的传输模拟。自加速过程模拟(Simulation of Airy Beam)

说明：  实现快速分数阶傅里叶变换功能。分数阶傅里叶变换是整数傅里叶变换的普遍形式，可用于光的菲涅尔衍射模拟。(The function of fast fractional Fourier transform is realized. Fractional Fourier transform is a general form of integer Fourier transform, which can be used to simulate Fresnel diffraction of light.)

matlab模拟几何光线追迹，计算双胶合透镜的像差(simulate the geometric ray tracing and calculate the aberration of double with matlab)

平面波从石英玻璃入射到空气中的P、S分量的反射波相位和透射波相位随入射角度的变化(The phase of the reflected wave and the phase of the transmitted wave of the plane wave from the quartz glass to the air in P and S vary with the angle of incidence.)

说明：  一个基于有限元方法的平面问题求解器，支持网格类型为二维四边形四节点单元和四边形八节点单元的有限元网格： 前处理——用Abaqus建模编号并导出数据 在Matlab中读取数据文件 计算单元刚度矩阵（采用高斯积分），组集结构刚度矩阵 组集结点载荷向量，引入位移边条 求解结点位移，单元应力应变 后处理——绘制应力应变位移云图，与Abaqus结果对照(A plane problem solver based on finite element method)
