【摘要】 对德令哈地震台2008年1月—2012年9月钻孔应变、钻孔倾斜、水温、地磁等前兆测项所受到的自然环境、人为、观测技术系统故障等干扰因素进行分析,认为:①自然环境干扰因素有人工湖、黑石山水库、巴音河和灌溉水渠等;②人为干扰因素有前兆仪器的维护维修、调零、标定等;③观测技术系统故障干扰因素有设计缺陷导致的供电故障、探头接触不良或漏油、仪器元器件工作状态的失稳等。更多还原

【Abstract】 The interference of borehole strain,borehole tilt,water temperature,geomagnetic precursory observation data from the natural environment,human interference factors and observation technology system failure at Delingha Seismic Station form January 2008 to September 2012 are analyzed.The results show that the main interference factors are:man-made lake,blackrock mountain reservoir,Bayin river and irrigation channels,etc of natural environment interference factors;precursor instrument maintenance,zero maintenance,calibration,etc of man-made interference factors;and power supply failure,poor contact probe or leaking,instability of the working state of equipment components,etc of observation technology design flaws system failure interference factors.更多还原
