摘要
陆壳为什么会产生运动？这是世界地学领域中一个没有解决的基本理论问题。我国是大陆为主体的国家，地域宽广，分布着许多典型运动的地块。仔细研究这些典型运动地块的运动方向和地球物理特征发现，其运动方向与地块的密度具明显的规律性。在相邻两地块中，密度大的地块缓慢的向极点运动，密度小的地块向赤道方向运动，从这一现象入手，研究了由于地块的密度变化造成受力条件的改变。并导致水平运动的力学机制。通过对天体形状的观察，提出了密度平衡椭球体观点。利用平衡椭球体、等势面、能量极值原理，从理论上阐明了密度变化导致水平运动的规律，进一步又用数学力学方法和大量的具体实例等，从各个侧面，终于证明了地球表面地块密度变化导致水平运动的规律。这一理论的提出，使地学领域中许多难以解释的现象，如我国大量花岗岩体向南推覆，南极冰盖移动问题，水库地震产生的原因等得到了答案。
The force to drive crustal movement is the basic theory in the domain of geonomy,butit didn’t settle yet till the present.In the course of inquiring into the force to drive crustalmovement,firstly,the author studied the shape of celestial body and discovered that theshape of body is not only under the influence of rotation of the body,but also under theinfluence of the density.Results show that the higher the density,the smaller the oblateness.Secondly,the author advanced the concept of“density equilibrium ellipsoid”.Usingequilibrium ellipsoid and equal potential energy plane expounded that if partial density ofmassif in the crust suddenly becomes higher,it will slowly move to the polar;while thedensity of massif becomes lower,it will move to the equator.Magma activity is the mainfactor to make density change.At last,the author proved this theory by methods ofmechanics and mathematics,and gave a number of examples.
