The anomalous variations of micro-current before this two earthquakes are obvious. The anomalous amplitude is 10~20 times higher than that of ordinary background.
大地微电流在这2次地震前具有明显的异常变化，其异常幅度达正常背景值的10~20倍。
The longitudinal bias stress may always weaken the anomalous amplitude-dependent effect, while the torsional one may induce different effects from different directions applied.
纵向偏应力总是削弱反常内耗效应，而切向偏应力因施加方向的不同引起不同的内耗效应。
Peaking effects were found on the plot of internal friction vs strain amplitude or time when the resonant frequency of anomalous peak closed to the normal one.
当反常共振峰频率与正常共振峰靠近时，在内耗-振幅或内耗-时间图上呈现峰值效应。
