计算动力学研究，应力波引起的裂纹扩展问题，供大家学习(Kinetics calculations, crack propagation problems caused by stress wave for everyone to learn)

ADINA 系统是一个单机系统的程序，用于进行固体、结构、流体以及结构相互作用的流体流动的复杂有限元分析。借助 ADINA 系统，用户无需使用一套有限元程序进行线性动态与静态的结构分析，而用另外的程序进行非线性结构分析，再用其他基于流量的有限元程序进行流体流动分析。此外， ADINA 系统还是最主要的、用于结构相互作用的流体流动的完全耦合分析程序（多物理场）。(ADINA System is a stand-alone system program for performing complex fluid flow finite element solid structure, and fluid structure interaction analysis. With ADINA system, users do not need to use a finite element program linear static and dynamic structural analysis, but with additional nonlinear structural analysis program, and then the other program flow based on finite element analysis of fluid flow. In addition, ADINA system or main, fully coupled analysis program for fluid flow structure interaction (multi-physics).)

用mfc实现计算器的基本操作，支持键盘输入，并保留xp风格,可计算平方，幂，时间显示等操作(With mfc achieve the basic operation of the calculator, support for keyboard input, and retain xp style, calculates the square, power, time display and other operations)

运用矩阵摄动法求解结构的复模态参数与动力特性等(Application of Matrix Perturbation Method for Solving Complex Modal Parameters and other dynamic characteristics of the structure)

小波包分析提取振动信号中的特征频率，微分方程组数值解方法，有循环检测，周期性检测。( Wavelet packet analysis to extract vibration signal characteristic frequency, Numerical solution of differential equations method, There are cycle detection, periodic testing.)

电力芯片RN8302计算高次谐波时的FFT变换算法，最高可实现51次谐波计算。(FFT transform algorithm for power chip RN8302 to calculate the high harmonics, the highest can achieve the 51 harmonic calculation.)
