宝昌地震台VP型垂直摆倾斜仪常见干扰

收集并整理内蒙古自治区宝昌地震台VP型垂直摆倾斜仪数字化观测资料，通过调查各种干扰因素特征，分析认为，雷电和强降雨、温度与气压、标定与校准、仪器故障是影响倾斜仪观测的主要因素。对干扰因素进行识别，进一步增加垂直摆观测数据可用性，对于准确抓取短临地震异常信息具有一定实用意义。

Analysis of the common interference factors of the VP vertical pendulum tiltmeter at Baochang Seismic Station

In order to carry out this project and write this paper, we collect and analyze the digitized data of the VP vertical pendulum tiltmeter at Baochang Seismic Station, Inner Mongolia Autonomous Region. We analyze and induce all these interference factors for the VP vertical pendulum tiltmeter, and through investigate these factors, we found four causes of the inaccurate observation. They are thunder and heavy rainfall, temperature and atmospheric pressure, calibration and malfunction. In order to make the observation data more accurate, we analyze and modify these factors. This project will make contributions to the observation of short-term macroscopic anomalies and seismic anomalies before an earthquake.
