【摘要】 地球自转速度变化所产生的动力，可以使地球的岩石圈、水圈、气圈、生物圈物质发生异常性的运动和变化，从而引发地震、海洋灾害、气象灾害和生物灾害；它又使这些灾害彼此之间具有密切的内在联系和大体相同的韵律活动。这一特点在认识自然灾害发生发展规律和进行灾害综合预报时是非常重要的。更多还原

【Abstract】 The motive force resulting from earth’s rotation speed variations may cause abnormal materialflows in the lithosphere, hydrosphere, atmosphere and biosphere, thus inducing seismic, oceanicmeteorological and biological hazards. These hazards show close inherent interrelations and roughlyidentical rhythmic activities. This chracteristic feature is of great importance to the understandingof the occurrence reoccurrence regularity of natural disasters as well as to the synthetic disasterforecasting.更多还原
