    • Abstract
  • 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.
