PRELIMINARY RESULTS OF GRAVIMETRIC EARTH-TIDE MEASUREMENTS IN BEIJING |
|
| Abstract: | This work introduces results of gravimetric earth-tide measurements from October 10, 1977 to May 3, 1978 in Beijing. The gravimeter used in the measurement is Askania GS-15 No. 231 and is installed in thermostatized underground room (at a depth of 4m) with an annual temperature variation of less 1℃ and moisture of less 70%. The station is located at 39.97°N lat., 116.42°E long, with an elevation of 45m. The chart speed is about 30mm per hour. The sensitivity of the recorder scale is about 2μgal |
