采用离散的数值方法，通过坐标转换并生成贴体网格系统，计算轴对称喷管流场(Discrete numerical methods, through coordinate transformation and generate body-fitted grid system, calculating axisymmetric nozzle flow)

矩阵转换问题 行与列的个数均为n 的矩阵称为n 阶方阵。假定矩阵中的每个元素的值在0到9之间，则可以将矩阵中的所有元素按行依次排列得到一个“单行矩阵字符串”。(Matrix conversion, the number of rows and columns of the matrix n are called n-order square. Assume that each element of matrix value in the 0 to 9, you can press all the elements of the matrix rows in order of priority for a " single matrix string." )

这是用C++编写的 用高斯方法求解方程的方法 我想对与计算机数学的同学来说 可能会有用(It is written with C++ method for solving equations using Gaussian approach I want to mathematics and computer may be useful for the students)

用Fluent VOF模型模拟单个小水滴落入盛水的水杯之中(Fluent VOF model simulations using a single drop falling into a water glass)

盒维数计算和豪斯多夫维数的计算与应用研究程序(box counting)

ansys 求解桥梁结构弯矩响线的命令流，非常实用(ansys solving the stream of the bridge structure bending ring line command is very useful)

计算日期时间，可以显示不同颜色，主要用以计算上班日期，换班日期，十分方便。(Daliy Calc)

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：  用C语言编写多元线性回归方程，写得不好的地方请指教！(Using C language multiple linear regression equation, where poorly written, please advice!)

说明：  fortran弹塑性分析程序，很有用的啊！(fortran plastic analysis program, very useful)
