SSQ-Ⅱ双轴气泡倾斜仪及其调和分析

SSQ-Ⅱ双轴气泡倾斜仪,在全国倾斜仪器比测中,其灵敏度达10-9量级,漂移量小,固体潮汐记录清晰,M2波值精度能够满足我国Ⅰ类台的要求。 根据1983年12月——1984年5月,共6个月在徐州比测的资料,用维涅第科夫法进行调和分析,M2波的达0.004,S2波的为0.009。 

SSQ-II BIAXIAL BUBBLE TILTMETER AND HARMONIC ANALYSIS

The SSQ-Ⅱ biaxial bubble tiltmeter was successful in taking part in the comparison test of dltmeters from all parts of China at the Xuzhou Observatory.Its sensitivity reaches the order of 10-9,and the zero drift is rather small. It can clearly record the crustal tide. The value of M2 wave can meet the requirements of first class observatories in China.By using the data of six months (1983.12-1984.5) from comparison test at the Xuzhou observatory some harmonic analysis with the Venedikov method was carried out. The result is that the △ value of M2 wave reached 0.004,while that of S2 wave reached about 0.009.
