【摘要】 用MY—1BH型地形变遥测记录仪可以实现水平摆地倾斜观测的遥测可见记录。本文给出在楚雄地震台,两套MY—1BH分别配SQ70B石英水平摆和JB金属水平摆的观测结果:光杆都为2米,记录格值分别达到0.001角秒/毫米和0.002角秒/毫米;潮汐因子r（M₂）精度达到Ⅰ类台站要求;配SQ70B的r（M₂）值,1984年全年变化最大为3％。更多还原

【Abstract】 Using MY-1BH ground deformation instruments together with telerecorders, it is possible to obtain visual recordings in the observations by the horizontal pendulum tiltmeters. This paper illustrates our result at Chuxiong Station where 2 sets of MY-1BH instruments arc respectively connected io a SQ70B quartz horizontal pendulum and a JB metal horizontal pendulum, as shown in the following: a) The lengths of the light beam are all 2m, the recorded calibration values respectively reach 0.001"//mrn and 0.002"/mrn; b) Precision of tidal factor r(M2) has reached the standard for class I stations, c) If helped with r(M2) value by the SQ70B instrument, the maximum annual change in 1984 is 3 %.更多还原
