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. In the case of that the measurement is in the stable geological conditions and the smaller environment noise, the action of vibration isolating spring is not obvious, but it yields greater effects on measurement accuracy.

通过在环境干扰较小的九峰站观测实验，得到如下结论：在正常大气压状态下所观测到的空气阻力影响约500×10-5ms-2，比理论估算值大近30×10-5ms-2，若在低真空状态测量空气阻力也将产生2.3×10-5ms-2观测误差；落体室真空度维持系统工作不正常，空气阻力也将对重力观测造成0.1~4.1×10-5ms-2的观测误差；在地质条件比较稳定，环境震动干扰较小的基墩上测量，隔震弹簧的作用对观测结果影响不明显，但对测量精度影响较大。
