摘要
利用数学统计方法及调和分析精确计算仪器稳定性指标,对乌什地震台数字化水管倾斜仪2009年1月—2014年12月观测资料的运行、变化趋势和受干扰情况做初步分析,结果显示:(1)乌什地震台DSQ水管仪观测资料连续,仪器精度高,稳定性好;(2)影响水管仪内精度的干扰因素较多,其中水质变坏,多次更换维修更换液体的影响程度最高;(3)通过多次震例总结,说明乌什地震台水管倾斜仪具有一定的地震前兆异常监测能力。
A preliminary analysis for digital water tube tihmeter from January 2009 to December 2014 observations run, trend and interference of Wushi Seismic Station, using statistical methods and reconcile analysis calculated instrument stability index. The results show that Wushi Seismic Station DSQ water tube tihmeter observations continuous, high instrument accuracy and good stability. There are many interference factors to influence the water tube tiltmeter accuracy, and water quality deterioration, several repairs and replace liquid have the it shows that the water highest degree of influence. According to several summaries of the earthquake cases, tube tihmeter has anomaly monitoring capacity for earthquake precursors at Wushi Seismic Station.
