地球收缩运动的参数算法与阶段划分

THE PARAMETER ALGORITHM AND STAGE DIVISION OF THE EARTH CONTRACTION MOTION

地球收缩运动是人们最早认识的地壳构造运动之一。对因地球收缩所产生的周长改变量 (ΔL)、半径改变量(ΔR)、体积改变量 (ΔV) 等 ,分别建立了理论计算公式 ,并对公式中有关参数的取值办法作了说明。将地球在收缩力作用下发生收缩运动的过程分为四个阶段 ,即 :体积缩小的初始阶段 ,周长、表面积减小阶段 ,收缩力持续增大作用阶段 ,收缩力持续减小作用阶段。对地球收缩过程中发生的板块汇聚与冲撞进行了理论划分 ,认为板块之间的压缩效应可分为 6种 ,即 :上举式、下沉式、入覆式、包嵌式、推叠式。

The earth contraction motion is one of crust structure motions that people recognized first. To the parameters related to the earth contraction: perimeter variable quantity (ΔL), radius variable quantity (ΔR), volume variable quantity (ΔV) etc. Theoretical equations are formulated and relative parameter evaluation explained. The process for contraction is divided into 4 stages: volume-shrinking initial stage, perimeter and surface area diminishment stage, contraction force enlargement stage, contraction force diminishment stage. The assembling and collision of plates during the earth contraction process are divided theoretically. There are six types of compression effects between plates divides 6 sorts, that is raising mode, descending mode, covering mode, inlaying mode, push-overlaying mode, rivet groove mode and so on.
