| 摘 要： | 依据频率域磁化强度反演方法和程序，对唐山滦县震区航磁资料进行了数据处理，求取了该区视磁化强度的水平分布。反演结果反映了震区地壳内不同规模、不同物性的地壳岩体在平面上的投影。本文结合唐山滦县震区地震的时空分布及破裂方向，对该区地震的孕育及发生过程进行了探讨。

| Abstract: | In terms of inversion method and programme for frequency- domain magnetization intensity, airborne magnetic data from the Tangshan- Luanxian earthquake region are processed and the horizontal distribution of apparent magnetization intensity in this region is obtained. The inversion results reflect the project of the crustal rock masses with different scale and magnetism on plane in the earthquake region. With combination of time-space distribution and fracture direction of the earthquakes in the Tangshan-Luanxian region, seismogenic process in this region is approached in the paper. |
