摘　　要：对临汾地震台钻孔体应变仪观测资料从数据完整率、年零漂、观测精度、噪声水平、典型干扰等方面进行系统分析,结果发现:仪器正常情况下,观测资料完整性、精度、稳定性均符合观测规范技术要求。最近几年,在每年6-9月出现的数据大幅度阶变及高频抖动畸变疑与雷雨季节、仪器老化、传感器故障有关。The observation data of borehole strainmeter from the data integrity rate, baseline drifts, observation precision, noise level, typical interference and other aspects were analyzed systematically. The results show that the integrity of the observation data, precision and stability under normal conditions meet the technical requirements of the observation specifications. In recent years, step change of data and high frequency jitter that occur in June and September each year are related to thunderstorm season, instrument aging, and sensor failure.
