共有5个程序，分别是从文件提取散点画球（椭球），散点画压力云图，散点画散点位置及速度分布图，散点画密度分布图，以及从数据文件中提取特定散点的程序，这是一套程序，可对大量散点数据进行处理。-There are five programs, which are extracted from the file powder stippling ball (ellipsoid), scattered cloud pressure stipple, stipple scatter scattered distribution of position and velocity, bulk density stipple maps and data files extracted from the scatter-specific procedures This is a process, a large number of discrete data can be processed.
