光纤型SPR传感器的透射谱，通过最为常见的SP理论，使用MATLAB模拟器透射谱情况。(Transmission spectrum of fiber optic SPR sensor)

说明：  惯导解算，速度更新，位置更新，卡尔曼滤波(INS hen for the whole navigation system, the modules of trace-generation and SINS calculation are programmed using Matlab language.)

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.)

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 process. Three kinds of aggregates with different particle sizes are randomly distributed. The process of simulating the concrete material. It is helpful to the subsequent finite element calculation.)

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

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.)

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.)

SIMPLE算法程序，peric教材的程序(SIMPLE algorithm code)

说明：  重磁异常正演方法，是在给定地质体的形状大小、空间位置及物性参数的条件下，求它外部空间任意点上的物理场值。(The forward method of gravity and magnetic anomaly is to calculate the physical field value at any point in the outer space of a given geological body under the condition of its shape, size, space position and physical parameters.)

说明：  基于晶体塑性自洽理论 vpsc 模拟多晶体塑性变形的织构演化(Texture evolution of polycrystalline plastic deformation simulated by vpsc based on crystal plasticity self consistent theory)
