本文所讨论的地球系统由水体及具较大流变性的粘弹性地球本体物质二大次级质点系构成。在短、长期不同效应作用下本体分别表现出固体和流体两种特性。地球系统的不平衡状态由短期效应导致次级质点系质心偏离原位置,从而产生次级质心复位力,其大小正比于次级质心偏移距离,长期效应则使地球物质在复位力作用下发生次级质心复位运动,本文简略证得次级质心复位力的客观存在性,并试图从理论上分析复位力和复位运动存在的合理性。
The Earth system discussed in this paper consists of two major secondary particle systems of water body and viscoelastic earth body material with larger rheology. In the short, long-term effects of different effects under the body showed two characteristics of solid and fluid. Due to the short-term effect, the imbalance of the earth system causes the centroid of the secondary particle system to deviate from the original position, resulting in a secondary centroid reset force whose magnitude is proportional to the secondary centroid offset distance while the long-term effect causes the Earth’s matter to take place under the action of the reset force In this paper, we briefly demonstrate the objective existence of secondary centroid reduction force and attempt to theoretically analyze the rationality of the existence of reset force and reduction exercise.
