用平面波展开法计算二维声子晶体带隙,可直接计算得到多重分形谱,计算互信息非常有用的一组程序。( Computation Method D phononic bandgap plane wave, It can be directly calculated multi-fractal spectrum, Mutual information is useful to calculate a set of procedures.)

采用数值模拟方法对风一车一桥耦合系统的车桥气动特性进行分析研究，模拟计算了不同工况下车 辆、桥梁的气动力系数．分析了车桥问相互的气动影响，研究结果表明．车桥耦合系统与桥梁和车辆各自单体 相比较．气动力系数差异较大．故建议进行风一车一桥系统耦合振动分析时。车桥气动力系数应考虑车桥问 的气动影响．(The numerical simulation method axle aerodynamic characteristics of the the wind car bridge coupling system analysis, simulation under different conditions of vehicles, bridges aerodynamic coefficients. Analysis of the influence of the mutual pneumatic axle Q, the study results show that. The axle coupling system with the respective bridges and vehicles monomer comparison. Aerodynamic coefficients quite different. It is suggested that wind car bridge system coupled vibration analysis. Axle aerodynamic coefficients should consider impact of axle ask pneumatic.)

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." )

是用MATLABA编写的遗传运算发的一个小程序 挺好用的 大家(MATLABA is prepared by the genetic operator issued a small procedure very well, we try to use)

利用这个方法计算混沌时间序列的平均轨道周期p(Use this method to calculate the average orbital period of chaotic time series p)

求解O-S方程特征值，可以适用于多种条件下的O-S方程特征值计算(To solving OS Equation characteristic value, can be applied to a variety of conditions OS equation eigenvalue calculation)

说明：  Optics聚类算法 OPTICS没有显示地产生一个数据集合簇，它为自动和交互地聚类分析计算一个簇次序。这个次序代表了数据基于密度地聚类结构。它包含地信息，等同于从一个宽广地参数设置范围所获得的基于密度的聚类(Optics do not show clustering algorithm OPTICS to produce a collection of data clusters, it is automatically and interactively computing cluster analysis a cluster order. This order represents the data to cluster based on the density structure. It contains in information from a broadly equivalent range of parameters obtained by density-based clustering)

COMSOL_Multiphysics基本操作指南和常见问题解答，非常有助于帮助使用有限元建模的朋友！(COMSOL_Multiphysics basic instructions and FAQs, very helpful in helping friends using finite element modeling!)

根据X和Y两组数据，将两组数据在X-Y平面上最小二乘法拟合出圆(According to X and Y two sets of data, the two sets of data in the X-Y plane, the least square method of fitting the circle)
