| 摘 要： | 通过对徐州地震台YRY-4分量钻孔应变仪观测资料进行整理，对干扰因素进行简要分类并描述其主要特征，分析应变仪在干扰环境下自检相关系数K的变化，讨论K值发生明显变化（即数据自洽性遭到破坏）的原因，论证是否由地震台站附近地震成核过程中震源区地层介质连续性遭到破坏所致。

| Abstract: | Through the arrangement of the observation data of YRY-4 type drilling strain meter, the interference factors are classified in brief and the anomaly characteristics are summarized. The change of self-checking K coefficient of strain meter under interference environment is analyzed. The reasons for the obvious K value changes are discussed, demonstrating whether it is caused by the damage of stratum continuity of source area during the process of earthquake nucleation. |
