| 摘 要： | 本文通过对长春净月地震台TJ-ⅡC型体应变仪观测资料（从安装初期到正常工作及记录到大量应变地震波）的分析，针对台站观测工作中遇到的实际问题（漂移、突跳、阶跃、地震异常及干扰），对各种现象作了较为系统的归纳。如何正确理解这些丰富的信息，是准确识别震前异常的前提和基础。如何将干扰因素与地震前兆异常进行区分，将其从观测资料中剔除，将成为今后很长一段时间内台站工作的重中之重。

| Abstract: | In this paper,various phenomena(derivation,catastrophic jump,factorial jump function,seismic anomalism and disturbance) which occured in practical monitorings and observations are systematically concluded by analysing the materials derived from the volumetric strain instrument of TJIIC in Jingyue Earthequake Station,Chang Chun.That how to correctly understand these abundant informations will be the prerequisite and basis to accurate recognization of pre-seismic abnormality.Over a long period of time in futu... |
