摘要：Tidal variation of gravity was observed in Syowa Station, Antarctica, by means of LaCoste gravimeter G-118. It was carried out by visual reading at intervals of about one hour during a period of 7 days from June 18, 07h to June 25, 07h, 1968 (UT), the number of reading attaining to 169. The data obtained and the corresponding computed tides on a perfectly rigid earth were analyzed by the method of least squares and were compared with each other. It was then found that the tidal factor of gravity and phase lag are 1.376 and -3°.73 for K_1 constituent and 1.145 and -3°.16 for O_1 constituent, respectively.
