| 摘 要： | 对《地球演化》一书中的某些重要论点提出质疑。认为运用角动量守恒原理应考虑其适用条件，这一定律不适用于地球核幔体；核幔体与岩石圈之间能否作相对运动尚有待证实；地壳运动的总趋势是逐渐减弱而不是逐步增强。

| Abstract: | In this paper,the author put some questions to the important arguments in Earth Evolution.It is presented that the suitable condition must be considered when the law of conservation of angular momentum is used for the earth, that the law is not suitable to earth's core-mantle body,the relative movement of both the body and the lithosphere needs to prove,and that the tendency of crustal movement is gradually weaken but not strengthen. |
