    摘要:

    本文基于2008-2018年数据跟踪分析产品,通过分类归纳总结,分析新疆区域电磁仪器的8类环境干扰因素。通过对干扰成因的分析,列举具体典型事件,分析各类环境干扰事件的数据曲线形态及变化特征,为新疆区域有相同手段的台站在数据跟踪分析中提供有效事例和参考。同时,根据新疆区域8类环境干扰因素的成因和数据曲线变化特征,为进一步提取地震前兆异常信息,分析和应用电磁观测资料进行地震预报提供可靠依据和参考价值。

    Abstract:

    This study analyzes and summarizes eight types of environmental factors disturbing electromagnetic instruments in the Xinjiang region based on measurements obtained from data tracking and analysis products from 2008 to 2018. After analyzing the interference causes, specific typical events are determined, and the data curve shape and variation characteristics of various environmental interference events are investigated. This study provides effective examples and references for data tracking analysis at stations using the same observational means in the Xinjiang region. Furthermore, the causes of the eight environmental disturbance factors and the characteristics of data curve changes in the Xinjiang area can be used as a reliable base and as a reference for the further extraction of earthquake precursor anomaly information and earthquake predictions.
