地震前的地磁现象已引起国内外广大地震工作者的重视,现将苏联科学院编《地球物理学》一九七九年第三期上刊登的这篇文章译载于此,供参考.原文的作者是阿尔别洛维奇(Л·С·Алперович)、格赫别尔克(М·Б·Гохберг)、沙洛钦(В·М·Сорокин)、费道洛维奇(Г·В·Фидрович).此文研究了与地震同时发生的声震动引起的地磁变异的可能性,认为地磁场发生的变异是由于声脉冲进入非均匀的等温电离层的结果,证明了这种非周期地磁变化的持续时间为1±10分、幅度～10γ.原文在论述地磁异常时进行了较严密的数学证明.微引了14篇文献,因限篇幅,文献译文从略.
The geomagnetic phenomenon before the earthquake has aroused the great attention of earthquake workers both at home and abroad. Now, the article published in the third issue of the journal Geophysics of the Academy of Sciences of the Soviet Academy of Sciences is here for reference. The authors are composed of Árbilovich, Öber ÖÐÐÐÐÐÐÐÐÐÐÐÐÐÐ ÐÐÐÐÐÐÐÐÐÐ, ) .This paper studies the possibility of geomagnetic variation caused by acoustic vibration occurring simultaneously with the earthquake, and considers that the variation of geomagnetic field is the result of the acoustic pulse entering into the non-uniform isothermal ionosphere. It is proved that this non-periodic geomagnetic variation The duration is 1 ± 10 minutes and the amplitude is ~ 10γ.The author has carried out more rigorous mathematic proof when discussing the geomagnetic anomaly.We cited 14 articles because of the limited space and omitted the translations.
