中文摘要：

介绍了当前用于粒子加速器准直测量及监测地球潮的静力水准系统。根据地球潮汐（包括海洋潮和固体潮）理论,分析了地球潮汐对静力水准系统的影响,并对获得数据进行频谱分析,得出潮汐周期约为11.6、23.1和7.7 h,即半日潮汐、周日潮汐、1/3日潮,初步验证了地球潮汐对HLS的影响。

英文摘要：

Hydrostatic leveling system, used mainly in survey and alignment technology in particle accelerator and monitoring the tides is introduced in this paper. Based on the theory about the ocean tide and earth tide, we analyze effects of the earth tides on a hydrostatic leveling system. From the data obtained from an HLS, and their F are, and finally we verify the influence of the tides of planet earth.
