摘要
利用狮泉河台站一年数据,对Venedikov和Eterna两种调和分析方法进行了比较。发现对于观测时间较长的数据,Eterna方法的总体方差值要优于Venedikov方法的总体方差值,因此对于弹簧重力仪的连续观测时间较长的数据适合用Eterna方法进行调和分析,连续观测时间较短的数据适合用Venedikov方法进行调和分析。
In order to obtain more accurate values of tidal factor for high-precision geoscience, comparative study through the harmonic analysis of data of an year at Shiquanhe station, a comprehensive comparative analysis of methods Venedikov and Eterna is carried out. The results show that for the data observed in a longer time the population varience with Eterna method is better than that with Venedikov method, so for the harmonic analysis of the data onserved in a longer time, the Eterna method is suitable, and the Venedikov method is suitable for data in the shorter time.
