地震记录的数据，可以用来绘制地震记录，也可以作为地震反演的数据(Seismic wave inverse time migration program can realize the inversion of seismic wave)

计算声发射时域信号特征值：裕值，振幅因子FK、fc，峭度，(Calculation of acoustic emission time-domain signal characteristic values: margin value, the amplitude factor FK, fc, kurtosis,)

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.)

多物理场耦合软件采用有限元方法模拟rtfindgen(Coupled multi-physics simulation software using the finite element method rtfindgen)

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." )
