Surrounding the focus, anomalous velocity structures which exhibit apparent differences along with special and complex geological tectonic environment mean that these parts are favorable for earthquake occurrence. 震源区周围差异明显的速度异常结构和特殊而复杂的地质构造环境意味着这些部位是发生大地震的有利部位;
The relations between SIP real parameters of underground anomalous body and apparent complex resistivity spectra can be expressed by the combination of Cole-Cole models and dilute coefficient. 利用Cole-Cole模型组合和稀释系数理论,可以描述测量得到的视复电阻率频谱与地下多个电性体SIP真参数之间的正演关系。
The results show that there is the geomagnetic anomalous variation before earthquakes and the variation is complex. 结果表明,震前存在着地磁异常的变化信息,反映出地磁异常的复杂性。
