摘要
目前多数地球科学家认为 ,地球的演化 (包括地壳运动和地震活动 )是由地球内部因素决定的 ,地球外部因素是次要的 .地球虽是庞大并具有确定边界的星体 ,但从银河系看来 ,地球不能作为单独的星体存在 ,它必须依附太阳系才能生存下去 .因此 ,研究太阳活动、太阳能量向地球的输送及太阳与地球间能量 (包括动量和质量 )相耦合的物理机制 ,是研究地球演化的具体途径 .应用地壳“轧展”效应理论 ,对地壳运动的成因及地壳内部的应力积累进行了探讨 ,并定量分析了地壳“轧展”效应在地壳表面的分布规律 ,首次从理论上推断出全球强震活动的控制因素 .该控制因素得到实际观测资料的证实 ,也为日地间能量相耦合的物理机制———地壳被“轧制”
It is considered that the earth should not have existed as an independent planet in the whole galaxy system, although the earth is gigantic planet with its definite margins. In this sense, the survival of the earth should be dependent on the solar system. The research into the solar activity, transmission of the solar energy from the sun to the earth, and the physical mechanism for the coupling in energy (including momentum and mass) between the sun and the earth, is a practical approach to research into the evolution of the earth. This paper presents the application of the crustal “rolling and extending” effect theory to the discussion of the origin of the crustal movement and the stress cumulation inside the crust. Following the “rolling” mechanism of the crust, the distribution pattern of the crustal “rolling and extending” effect is quantitatively analyzed on the surface of the crust. Furthermore, the controlling factors of global strong earthquakes are theoretically inferred for the first time. The controlling factors proved by the observed data, provide us with the theoretical and observed evidence for the existence of the physical mechanism of the coupling in energy between the sun and the earth — the “rolling” mechanism of the crust.
