摘　　要：本文在统一了弥漫、下关(相距60km)两台站标定常数、标定方法和计算方法的基础上,讨论了两台站的重力固体潮观测结果(其中下关台14个月,弥渡台两年);确定了滇西地区GS15重力仪所观测到的主波潮汐因子的最佳值。文章最后分析了澜沧地震前后下关和弥渡台潮汐和非潮汐变化特征。In this paper,on the basis of unifying the calibration constand and method, and the calculation method of Midu and Xiaguan stations (the distance of two stations is 62 km), the results of a year's earth tidal observations at two stations arc discussed, and the optrmun values of earth tidal factors for gravimeter GS15 in the west Yunnan province are determined.At last,the change characteristics of earth tide and non-tide at Midu and Xiaguan stations before and after the earthquake Lancang (M7.6 are analysed.
