说明：  该程序文件包以WOA数据库黑潮区域春夏秋冬海表温度数据读取绘制平面图像为例，读取csv文件数据绘制全球海表温度SST平面图，同样适用于一般csv文件的读取与图像绘制，提供一种构造格点矩阵放置散点数据的思路。
(This program file package takes the reading and drawing of flat images of SST data of spring, summer, autumn and winter SST data in kuroshio area of WOA database as an example, reads CSV file data to draw SST plan of global SST, which is also applicable to the reading and drawing of general CSV files, and provides a way to construct lattice point matrix to place scattered point data.)
