J2流动理论加上破坏失效判据的程序，用于ABAQUS中的vumat程序，功能模拟加载到失效破坏的过程(J2 flow theory coupled with damage failure criteria of the program for the vumat ABAQUS program, functional simulation load to failure of the process of destruction)

一个短时傅里叶变换的C语言实现，对3万个数据进行加窗、FFT处理(A short time Fourier transform of C language, for 30,000 data windowing, FFT processing)

说明：  应用改进的CC法求取时间延迟和嵌入维数，效果不错(The modified CC method to strike a time delay and embedding dimension, good results)

说明：  数值分析中的chebyshev拟合程序，学习数值分析的同学可以参考参考(Numerical Analysis of chebyshev fit program, students study and numerical analysis can refer to reference)

自己实现的一个简单的计算器，支持大数的加减乘除、开平方等操作，不适用库函数。(Themselves to achieve a simple calculator, to support the addition and subtraction, multiplication and division of large numbers, such as square root operations, library functions do not apply.)

计算正交各向异性材料（如木材，复合材料等）的弹塑性本构(The elastoplastic constitutive relation of orthotropic materials is calculated)

利用Abaqus子程序UAMP实现PID控制。(PID control is implemented using the Abaqus subroutine UAMP.)

本程序用于实现快速傅里叶变换的快速算法 ％ 为代码简便所有*2操作均直接实现，实际应采用二进制左移实现 (This procedure used to realize fast Fourier transform fast algorithm of all the code is simple to operate* 2 are referred directly to realize the actual binary left should be used to achieve)

利用MATLAB实现了16位快速傅立叶变换，并与自包含函数进行了比较。(The 16-bit Fast Fourier Transform is realized by using MATLAB and compared with the self-contained function.)

用于测试hadoop的mapreduce功能，功能与自带的wordcount程序大相径庭。(Use to test the mapreduce function of hadoop,this program was seem to the origin program.)
