摘要
兰州十里店地震台于1985年安装了1台SSY-Ⅱ石英伸缩仪,于2006年又安装了1台SS-Y伸缩仪。对这两套仪器的主要构造部件——基线、换能系统、标定系统进行了对比分析,并从产出资料的趋势变化、调和分析、干扰、地震事件等方面进行了对比分析,总结了这两套仪器各自的优缺点。
An SSY-Ⅱ quartz extensometer was installed in 1985 at Shilidian station in Lanzhou, Gansu Province and an SSY-Y extensometer was installed again in 2006. In this paper, the contrastive analysis was made to the main parts of the two sets of instruments, such as the base line, the transducer system, the calibration system, the trend variation of the output data, the harmonic analysis, the interference and the seismic event. Also, the advantages and disadvantages of each instrument were pointed out.
