摘要
对6台CG型重力仪分别进行静态和动态稳定性试验,结果表明,CG-6型重力仪继承了CG-5型重力仪的静态稳定性优点,静态曲线拟合成直线的拟合中误差小于3μGal,最大拟合差小于5μGal;CG-6型重力仪动态精度和动态零漂率明显优于CG-5型重力仪。
In this paper,the static stability test and the dynamic stability test are carried out on the six CG gravimeters.The test results show that the CG-6 gravimeters inherits the static stability advantages of the CG-5 gravimeters.The error in the fitting of the static curve into a straight line is less than 3μGal,and the maximum fitting difference is less than 5μGal.The dynamic accuracy and dynamic zero drift rate of the CG-6 gravimeters are significantly better than the CG-5 gravimeters.
