Abstract In order to obtain more accurate values of tidal factor for highprecision 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.
Key words ：
