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/mm. Hourly reading errors are less than 1μgal. The sensitivity calibration of the instrument is checked every fortnight by means of the electromagnetic calibration equipment. The instrument time constant is 54 sec. The scale value of the gravimeter was calibrated at the National Gravimetric Datum Level. The harmonic analysis of the records is made by the method of Venedikov with the Cartwright-Tayler-Edden complete tidaldevelopment. The results of amplitude coefficient δ and phase lags κ for main tidal wave in Beijing are as follows: δ（O₁）= 1.1639 ± 0.0086, κ（O₁） = 0.44°±0.42°,δ（M₂） = 1.1593±0.0027, κ（M₂）=-0.40°±0.13°.
