中文摘要：

介绍FG5-240对中国大陆及海岛17个测站进行绝对重力观测的情况，并对观测结果进行分析。结果表明FG5-240具有良好的稳定性，观测精度优于±5．00×10^-8ms^-2，满足绝对重力测定技术要求。

英文摘要：

The absolute gravity measurements on the 17 fiducial stations in Chinese mainland and island using FG5-240 is introduced, and the measurement results are analyzed. The study shows that the characteristic of FG5- 240 is stable, the measurement precision is better than ±5.00×10^-8ms^-2, which satisfies the technology requirement of absolute gravity measurement.
