德令哈地震台水温对比观测分析

Analyzing on Comparison Observation of Water Temperature at Delingha Seismic Station

德令哈地震台水温仪自2007年5月运行以来,出现很多呈"急升"型的变化形态,为了判别水温变化是否为前兆异常,2013年4月20日在德令哈地震台水温井同一观测深度上安装了另外一套相同型号的水温仪进行对比观测。通过对产出的连续资料进行对比分析,认为两套仪器产出的观测数据真实可靠,温度变化趋势特征一致,是井下温度变化的真实反映。

The curve of water temperature had the variation form of a sharp rise recorded by Delingha Seismic station since the hydrothermograph was running since Apr.,2007.To determine whether the water temperature changes are precursory anomalies,another instrument of the same type of hydrothermograph was installed on Apr.20,2013 at the same observation depth at Delingha Seismic Station.By analyzing the continuous data recorded by these two sets,we discovered that the observation data was true and reliable,and the trends of temperature variation characteristics had the same step of these two sets,which reflected the real water temperature underground.
