利用波动方程的方法对地震波的传播过程进行模拟
在地震勘探中，我们可以利用正演程序实现野外资料采集的模拟，这个程序是利用波动方程的方法对地震波的传播过程进行模拟。(In seismic exploration, we can use the forward program implements the analog field data collection, this program is the use of the wave equation method for seismic wave propagation simulation.)

主成分分析(PCA)是一个数学的过程,它使用一个正交变换转换成一组观测到的可能相关的因素形成一套价值观的独立变量称为主成分。主成分的数量小于或等于原始变量的数目
(Principal component analysis (PCA) is a mathematical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of uncorrelated variables called principal components. The number of principal components is less than or equal to the number of original variables)
