According to the observation experiment at the Jiufeng station where there is smaller environment noise, the conclusions are drawn as follows.In the normal atmosphere, the observed value is about 500×10-5ms-2, which is greater than theoretical value about 30×10-5ms-2, and if in the low vacuum, the observational error about 2.3×10-5ms-2 is generated. The vacuum maintaining system in falling room can not work normally, which will yield 0.1~4.1×10-5ms-2 error to the gravimetric observation.
