光纤中的非线性光纤光学 光孤子的傅里叶接
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.)

飞秒及皮秒激光 高斯脉冲在光纤中的色散
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。啁啾型脉冲在光纤中传播，因色散作用及各种非线性作用谱线被展宽。(Ultra-short pulses are generated when the gain and loss of the cavity are balanced, and the dispersion and nonlinearity are balanced. Chirped pulses propagate in optical fibers, and their spectral lines are broadened due to dispersion and various non-linear effects.)

一维热传导方程_有限差分
分层的一维热传导方程的有限差分法MATLAB程序，是简单的显式差分格式，尽量使用了矩阵运算，没有符号运算。
文件chafen1.m以路面为例，假设有多层建筑材料，热传导系数已经在代码中给出。用户使用时请按自己需要修改chafen1.m文件，增减层数，修改热传导系数等即可。(One-dimensional heat conduction equation finite difference method MATLAB program, is a simple explicit difference format, as far as possible use of matrix operations, no symbolic operations
The file Chafen 1.m takes the road surface as an example, assuming that there are multiple layers of building materials, the thermal conductivity is given in the code. Users should modify the Chafen 1.m file according to their own needs, increase or decrease the number of layers, modify the thermal conductivity and so on.)
