大部分机械都是以转子形式运转，这本转子动力学是研究旋转机械动力学的基础(Most of the machinery are operating a rotor and the rotor dynamics is the study of the dynamics of rotating machinery foundation)

提供基二FFT(频域)的C语言算法,希望对大家有用()

用于弹塑性本构的切线刚度计算，基于塑性本构的增量理论编写(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)

说明：  三角网格以及矩形网格剖分. 实现等参单元以及误差L H 范数收敛阶估计.(Triangular meshes and rectangular meshes are subdivided to achieve convergence order estimation of error L H norm.)

运用格子Boltzmann方法中的伪势模型，模拟胀大平面流道中的两相流动，左边幂律流，右边牛顿流体。得出流动过程中，各个瞬态的结果。(Using lattice Boltzmann method of pseudo potential model to simulate the swell plane channel flow, on the left side of the power-law fluid flow. On the right side of the Newtonian fluid. In the process of flowing, the result of each transient.)

基于Python编写的用于曲线拟合，最小二乘法(Based on Python for curve fitting, least squares method.)

说明：  三维FMM射线追踪程序，计算得到核矩阵 时间场(Three - dimensional ray tracing program, the calculation of the kernel matrix)

说明：  编程观察无穷级数 1/n的收敛性。 采用 IEEE 单精度浮点数，观察当 n 为何值时求和结果不再变化，将它与理论分析的结论进 行比较 (注：在 MATLAB 中可用 single 命令将变量转成单精度浮点数)。(Programming observation of convergence of infinite series 1/n)

光纤激光器速率方程 修改数值后可直接计算(The fiber lasers rate equation)

《数字信号处理》一书讨论的内容，主要是离散时间信号的博氏变换和数字滤旋器，本书在该书内容的基础上，介绍了不再属于傅盟叶变换家族的另一种重要的变换一一希尔伯特变换。( Digital Signal Processing to discuss the contents of the book, mainly discrete-time signals and digital transformation Borrelia spin filter, and the contents of this book in the book, based on the introduction of the AU is no longer a Fourier transform Fu family, another important Hilbert transform 11.)
