本论文的主要工作在于引入了一种新的特征提取方法----独立分量分析。独立分量分析的根本原理是通过分析多维观测数据间的高阶统计相关性，找出相互独立的隐含信息成分，完成分量间高阶冗余的去除及独立信源的提取(In this paper, the major work is the introduction of a new method of feature extraction independent component analysis. Independent component analysis of the fundamental principle is that through the analysis of multi-dimensional data between the relevance of higher-order statistics, independent of each other to identify the implied message composition, the completion of inter-component higher-order removal of redundant and independent source extraction)

说明：  美国著名教授agrawal写的非线性光学原理及应用，是一本很好的学习非线性光学的书籍，里面包含了中文和英文版本(Written by American professors agrawal nonlinear optics and applications, is a good learning books on nonlinear optics, which includes the Chinese and English version)

说明：  该程序用来读取地震原始资料segy格式的数据，也可以增加些模块对数据进行处理(The program used to read raw data segy seismic data format can also be added so that the data processing module)

说明：  时间排序 (Time to sort)
