摘要：

Small drifts in gravity could, in principle, be used as a measure of vertical crustal motion. However, this could be the case only if other real and apparent causes of gravity variations can be identified and removed from data. We report here on work with the superconducting gravimeter. It measures the influence of atmospheric pressure variations on gravity and indicates that continuous gravity and pressure records are required in order to account for the effect at the 1 μGal level. In addition, we discuss some preliminary results with two instruments at the same location which suggest that gravity began to change at the rate of a few microgals per month during the measurements. © 1979.
