说明：  各种滤波器，包括高通、低通、带通等滤波器，可用，直接输入数值即可，可直接使用，没有bug(bandpass filter,Band pass filter, available, direct input value, can be used directly, no bug)

说明：  地球物理大师Claebout的几个有用的程序，包括偏移程序。用fortran语言写的(Several geophysical Claebout Masters useful procedure, including the migration process. Fortran language used to write the)

分析两时间序列之间的超前和之后关系，计算滞时长度，多用于水文气象方面分析研究(Analysis ahead of and after the relationship between the two time series, calculating the lag length, used for the analysis of hydrometeorological)

C-N解偏微分方程的程序。解的是定步长的抛物型偏微分方程： du/dx - a * d2u/dx2 = 0 在程序中可以更改 a 的值以实现不同系数的解。在循环中改变 a 的值以实现变系数. 该说明在压缩包是也有(CN solution of partial differential equations procedures. Solution is scheduled to step parabolic partial differential equation: du/dx- a* d2u/dx2 = 0 in the procedure can be changed in order to realize the value of a different coefficient of the solution. Change in the cycle in order to realize the value of a variable coefficient. The note in the compressed packet is also)

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)

说明：  用二分法求解一元五次非线性方程的实数解，在高等电路学习中有很好的用途。(One yuan of five nonlinear equations dichotomy solving real solutions, there is a very good use in the higher circuit learning.)
