【摘要】 泰安地震台为全国形变一类观测台。现有除重力仪、井下竖直摆外的几乎所有形变固体潮数字化观测仪器。通过对山东泰安台固体潮形变观测的数字化与模拟资料的一致性、精度和格值的对比研究 ,以及对数字化资料连续性、稳定性的综合统计分析 ,对各套仪器的运行状况进行了评价和论证。认为数字化与模拟观测资料的固体潮形态、观测精度、方差及均值无显著性差异。在数字化倾斜仪中 ,水管倾斜仪的稳定性及精度较高 ,石英摆存在一定程度的漂移 ,垂直摆倾斜仪的漂移较大、资料内精度较低。伸缩仪资料也存在精度较低的情况 ;压容及体应变仪资料内精度较高 ,但压容仪漂移较大 ,仪器稳定性不及体应变仪更多还原

【Abstract】 Tai’an Seismic Station is the first-class standard deformation surveying station in China. It has almost all of the earth tide instruments except for the gravimeter and under-well tiltmeter. By comparison with the coherence, accuracy and scale value of the digitized and simulated observations and analyses of the continuity, stability and synthetic statistics to the digital data, the operational state of the instruments has been evaluated and discussed. It is considered that the shape of earth tide, accuracy, error and mean value of the digital data have no obvious difference with those of the simulated data. For the digitized instrument, the stability and accuracy of the water-tube tiltmeter are higher than that of others. There exists a drift for the quartz pendulum tiltmeter. The vertical pendulum tiltmeter has bigger drift and with lower inner accuracy. The extensometer has a lower accuracy. Both of the piezo-capacity meter and the body strainmeter have higher inner accuracy. But the piezo-capacity meter has bigger drift and its stability is not good as the body strainmeter.更多还原
