【摘要】 简要介绍了姑咱台DSQ水管仪和SS-Y伸缩仪仪器"数字化"改造过程,以及模拟与数字化2种仪器并行记录的情况,并对模拟记录和数字记录的内在精度、漂移量、记录形态等指标进行对比分析,找出数字化观测与模拟观测的差异,为地震台站进一步搞好数字化观测,提高观测精度提供可靠依据。更多还原

【Abstract】 The digitization reforming process to the meters of DSQ tilt and SS-Y strain in Guzha Seismic Station and the recording results of these two meters are briefly described. The indexes such as the inner precision, the drifts of meters observing, observing data curves of the digital and simulative meters are discussed. We point out that digital meters have more advantages than simulative meters and some measurements to improving observing system are suggested as well.更多还原
