摘要
A10型绝对重力仪用于测量重力加速度(g),具有高精度、便携式和易操作等优点。介绍了A10的基本原理,并与FG5型重力仪进行了对比分析。基于A10/35绝对重力仪的室内和野外测量数据,分析了该仪器的稳定性和影响测量精度的主要因素。测试结果表明,不同环境下该仪器测量组间离散度均小于10×10-8ms-2,仪器性能稳定可靠。最后提出了实际使用的具体建议。
The A10 absolute gravimeter with a high precision ,high transportable and easy operating instrument is used to measure the acceleration of gravity （g）. The principal and differences of the A10 are introduced by comparing to FG5 absolute gravimeter. The stability and influencing factors of precision are analyzed based on real data tested both in door and field environment.Test results show that set scatter of this instrument is less than 10×10^-8ms^-2 in different environment, it is stable and reliable performance. Finally, some operational requirements are suggested in conclusion.
