摘　　要：基于Ｏ１波与Ｋ１波和Ｍ２波潮汐因子的比值，介绍了我国南北地震带及华北等地区９个重力台站（１０套重力仪）、１０个静水位井、１１个倾斜及线应变台站潮汐因子的空间分布特征。与莫氏地球模型对比，重力线应变和水位潮汐中，Ｏ１波与Ｋ１波潮汐因子的比值均显示了液态地核的振荡效应。倾斜固体潮中。In this paper, the spatial distribution characteristic of earth tides in the area of North-South Seismic Belt and North of China etc, including 9 stations of 10 set gravimeters, 10 stations of water level well and 12 tilt and line strain stations, is introduced. Comparing the results of gravity line strain and water level well with that of the theoretical value of Molodensky's Earth Model,the factors of O 1 / K 1 show obviously the dynamic effect of the liguid-state earth core. The observational results of tilt tides, especially north-south direction,are disturbed seriously by the geological structure environment near the stations.
