| 摘 要： | 国际固体潮中心（I.C.E.T.）设计了一套处理潮汐资料的计算程序。其中有一数据的准备部分,用Lecolazet（以下简称莱氏）提出的组合z1/25z6（y3-（y0/2））和z1/25对观测资料进行平滑处理。这种方法简便易算。本文给出的数字滤波器,平滑处理效果比前者更好。

| Abstract: | Venedikov's theory on digital filter has been used in this paper. Two digital fillers which can really filter all tide waves and drift have been calculated by this theory. Instead of usingLecolezat's combinations and , these filters have been used to smoothlytreat the data of the gravitational earth tide in Kunming region. The result thus obtained is better than that obtained by conventional method. |
