PCA技术的一大好处是对数据进行降维的处理。我们可以对新求出的“主元”向量的重要性进行排序，根据需要取前面最重要的部分，将后面的维数省去，可以达到降维从而简化模型或是对数据进行压缩的效果。同时最大程度的保持了原有数据的信息。 (A major advantage of PCA technology is reduce the dimension of the data processing. We can calculate the new " principal component" vector order of importance, according to need to take the most important part of the front, eliminating the rear of the dimensions, dimension reduction can be achieved to simplify the model or the effect of data compression . At the same time maintaining the greatest degree of the original data.)

这是在cnki上下载的关于gps伪卫星定位精度的文献，里面有matlab仿真实验操作，可以通过实验发现dop值影响定位精度(This is the download in CNKI on GPS pseudo satellite positioning accuracy of the literature, there are matlab simulation operation, can be found through experiments that DOP value affects the positioning accuracy)

在地震资料处理时，将su文件转换为segy文件，需要写道头和卷头，程序中有给出，其中一些读写segy文件的函数需要再行下载(When seismic data processing, the file is converted to segy su file, you need to write head and the volume header, the program has given some of which function to read and write files need to re segy download)

It is a signal processing project. It deals with the processing of electrocardiogram signals. The statement is in the enonce_presentation file. Several signal processing tools are used, as periodogram, correlogram. An algorithm to recover lost samples is implemented.
