说明：  源程序可以处理各种需要低通滤波的数据，笔者曾用它处理过气测录井数据。如果稍加变通还可设计出高通、带通、带阻滤波器。从而满足各种现场数据处理的需求。
(Source can handle the needs of low-pass filter the data, I have dealt with it gas logging data. If a little design modifications can also be high-pass, band-pass, band stop filter. To meet a variety of field data in order to deal with demand.)
