摘　　要：本文介绍了兰州地区历次重力固体潮测量的概况,给出了不同仪器历次测量所得的重力潮汐参数。对比分析了Geo—765重力仪和改型后的GS11—150重力仪观测资料月调和分析主波潮汐因子的重复精度,评价了改型后的GS11—150重力仪今后对兰州地区地震的监测能力。文中还给出了该仪器改型前在天水观测的部分结果。This paper gives an outline of historied observations of gravita-tional earth tide in Lanzhou, and the tidal gravity parameters measured by different instruments. Comparative analyses about observation data, monthly harmonic analysis, and repeated accuracy of major-wave tidal factor between GEO—765 and modified GS11-150 gravimeter are made. The seismic monitoring capacity by using modified GS11-150 gravimeter in Lanzhou is evaluated. Finally, the part of results measured by old GS11-150 in Tianshui, Gansu Province is also introduced.
