平面波展开法计算的二维声子晶体带隙，分别是正方与圆形散射体形成正方格子声子晶体，最后输出了能带图的数据，需要自己用画图软件画出来。(Plane wave expansion method to calculate the band gap of two- dimensional phononic crystals, which are square with rounded square lattice formed scattering crystal, the final output of the energy band diagram of the data, so you need to use drawing software drawn.)

时间序列中的自回归移动平均模型（ＡＲＭＡ），可以进行实时预测(A sequence of time regression moving average (ARMA) model, can real-time prediction)

五点三次法实现振动信号趋势项的消除， 1、 计算出数据的均值、均方值、方差 ； 2、 用matlab编制五点三次法消趋势项程序。 3、 在同一坐标下绘出消趋势项前后时域信号，并分析比较。 绘出消趋势项前后信号的自相关函数。( Five points three times a method to achieve the elimination of the trend of the vibration signal, 1, to calculate the mean of the data, the mean square value, variance 2, the preparation of the five points three times France extinction trend procedure using matlab. 3, plotted in the same coordinate consumer trends before and after the time-domain signal, analyzed and compared. Draw to eliminate the trend before and after the signal autocorrelation function. )
