摘要
为探寻太阳系天体位置的变化对大地震发生的影响,作者分析了1900-1996年发生在中国7级以上大地震的天体位置特征和引潮力.分析结果表明,太阳系天体的特殊位置的确对地震的爆发起到了一定作用,太阳系10个天体中,又以月亮影响最大,本世纪71%的大地震发生于赤白交角从极大变为极小时期,对引潮力的分析表明,其水平分力更易触发大震,这与大震时10个天体天顶距集中分布于40°─140°之间是一致的,文中对此作了初步讨论,认为天体引潮加速度触发地震不在于某一量值,而在于其变化量的大小.
To explore the effects of the changes in the positions of objects of the solar system on the occurrence of a major earthquake, the authors analyse the posihons characterishcs of the objects and the tide raising forces which changed when the major earthquakes of above magnitide 7 occurred in China from 1900 to 1996. The analysis results show that the particular posihons of the objects of the solar system definitely take some effects on the occurrence of earthquakes and among the ten objects of the solar system, the change in the moon has the greatest effect on an earthquake. 71% of the magor earthquakes of this centUry occurred during the change in the inclination between the celestial equator and the moon's path from the maximum to the minimum.The analysis of the tide raising forces also demonstrate the horizontal forces trigger the major earthquakes much more easily, which is inaccordance with that the zeniths of the ten objectS are concentratively distributed betWeen 40°and 140°. The preliminary discussion given in this paper shows that the tidal acceleration of the objects trigger an earthquake not by a certain value but by the amount of the change in the value.
