| 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.

| Abstract: | 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. |
