| 摘 要： | 收集并整理2018—2020年乌加河中心地震台VP型垂直摆、体应变仪、伸缩仪和水管倾斜仪等形变观测资料，分析归纳地球物理异常与各类干扰特征，自然因素、人为干扰和地球物理事件在观测曲线上主要表现为噪声大、阶跃、台阶、突跳、高频干扰和趋势性变化、同震响应等特征。不同观测仪器对各类干扰的响应不同，甄别并分析干扰特征及原因，可为准确识别各类形变干扰提供依据。

| Abstract: | This study analyzes and inducts main characteristics of geophysical anomalies and various types of interference by arranging the observation data of vertical pendulum, body strain, extensometer, and water tube tiltmeter at Wujiahe Seismic Station during 2018-2020. The main characteristics of interference and geophysical events on the observation curves are high noise, steps, highfrequency interference, trend changes, and coseismic response. Different instruments have different responses to various types of interferences. Identifying and analyzing the characteristics and causes of interference can provide a basis for accurately identifying the types of interferences for deformation stations. |
