基于汶川MS8.0地震前3天记录到的强空间电磁异常的观测事实,引用岩石压电效应模型和岩石受压产生的电子-空穴理论,尝试推算和解释汶川地震前产生的显著空间电磁异常现象的“能量源”问题.结果显示:在设定汶川MS8.0地震发震主断层所受最大水平主应力和断层表面积的情况下,根据理论模型模拟计算得出,当发震主断层在强压力作用下形成微破裂至宏观破裂发育产生主破裂前,断层表面积累的电荷带电量为106—107 C,产生的垂直地-气界面附加电场为107—108 V/m;主破裂发生时,断层表面电量可达108 C,电场强度高达109 V/m,断层输出电流量级达105 A.震源区地-气界面电磁场的增强,一方面引起地面附近大范围电磁观测参数的大幅度突变异常,另一方面加速震源区上空的气体分子电离,空气电离增强空气的电导率,促使电荷快速扩散至电离层高度,直接引起高空电离层参数的短时突变异常并经空间地震监测卫星记录到.
Based on the observed electromagnetic anomalies recorded in the strong space 3 days before the MS8.0 Wenchuan earthquake, the piezoelectric model of rock and the electron-hole theory of rock compression are used to calculate and explain the significant space electromagnetic The results show that under the condition of setting the maximum principal stress and the fault surface area of the main fault of Wenchuan MS8.0 earthquake, according to the theoretical model, Before the main fault ruptures under the action of strong pressure and develops micro rupture, the charged charge on the fault surface is 106-107 C, and the additional electric field at the vertical ground-air interface is 107-108 V / m. At the time of rupture, the fault surface energy reaches 108 C, the electric field intensity reaches 109 V / m, and the output current magnitude of the fault reaches 105 A. The enhancement of the electromagnetic field at the earth-atmosphere interface in the source region causes the electromagnetic parameters Greatly abnormity anomaly, on the other hand accelerating ionization of gas molecules over the source region, air ionization enhancing the conductivity of the air, causing the charge to rapidly diffuse to the height of the ionosphere, directly causing the parameters of the altitude ionosphere Short mutations and abnormal seismic monitoring satellites through space to record.
