| 重力检定场是校准重力仪的标准装置，主要包括重力长基线、重力短基线和动态检定场。相对重力仪一般作为校准重力短基线和动态检定场的传递标准，也可用于重力长基线的检核设备，其技术性能必须满足重力检定场和测量标准的要求。本文分析CG-5相对重力仪的重复性、稳定性、测量不确定度和多台设备的测量结果一致性，论证其作为校准重力基线的可行性。 |

| The gravity field for testing gravimeters is a standard device to calibrate gravimeters, and it mainly consists of gravity long baseline, gravity short baseline and dynamic calibrate field. The relative gravimeter is usually used to calibrate gravity short baseline and dynamic calibrate field, and also can be used to check equipment of gravity long baseline. Its technical performance must meet the requirements of testing gravity and measurement standards. The paper analyzes the repeatability, stability and uncertainty of CG - 5 relative gravimeters, as well as the consistency of results of multiple devices, and demonstrates the practicability of CG - 5 relative gravimeters to calibrate the value of gravity baseline. |
