用于模拟混凝土单元的弹塑性模型，并有损伤变量，在ABAQUS中umat中输入弹性模量，泊松比与屈服应力即可。(The elastic-plastic model for the simulation of concrete unit, and the damage variable in the ABAQUS umat enter the elastic modulus, Poisson' s ratio and yield stress can be.)

二维弹性波正演程序，是在win7下Fortran编译器实习的(Dimensional elastic wave forward procedure, is under win7 Fortran Compiler internship)

用来计算航天器再入质点弹道，其中包括插值算法，龙格库塔法以及大气模型(Used to calculate the particle trajectory of spacecraft re-entry, including the interpolation algorithm, Runge-Kutta method as well as atmospheric model)

MFC实现快速傅里叶变换（FFT）MFC实现快速傅里叶变换（FFT）(MFC MFC Fast Fourier Transform (FFT) fast Fourier transform (FFT))

该程序用来对多种物质混合物吸收光谱数据进行分析，拟合出光谱曲线并且得到其各个峰值位置所在。(The program is used for a variety of mixtures of substances absorption spectral data analysis, curve fitting, and by their spectral location of each peak.)

最新版的oofem 可以自己加入一些材料模型 版本更新速度也算快(latest version of oofem )

说明：  用于对ADC采集正弦波后得到的数据进行FFT，计算得到ADC的动态性能参数(ADC DYNAMIC TEST(FFT))

比特交织编码中的迭代解映射算法简化 复杂度比原算法降低(Bit interleaved coded mapping algorithm in the iterative solution simplifies complex than the original algorithm reduces)

巨正则系综蒙特卡罗算法的源程序；可以用来进行吸附等分子模拟；最大的好处在于可以插入或删除原子(Grand canonical ensemble Monte Carlo algorithm source can be used for adsorption, molecular simulation biggest advantage is that you can insert or delete atom)
