全球构造由相对稳定的单元和相对活动的单元所组成。稳定单元称为板块构造或简称为板块。它与下面地幔对流体封闭系统的平流位置相对应。活动单元称为板边构造或简称为板边.它与下面地幔对流体开放系统的升流或降流位置相对应。张性板边因地幔升流推动两侧板块向压性板边运动。压性板边因地幔降流使两侧板块聚合、俯冲和碰撞。这就构成一个构造圈物质不断新陈代谢的运动系统,或称为构造圈内动力系统。
The global structure consists of relatively stable units and relatively active units. Stable cells are called plate structures or simply plates. It corresponds to the advection of the lower mantle to the fluid confinement system. The moving unit is called the plate edge structure or simply the edge of the plate, which corresponds to the upflow or downflow position of the open fluid system below the mantle. Due to the upwelling of the mantle, the slippage plates push the plates on both sides toward the pressure plate edge. Pressure plate edges due to mantle flow so that both sides of the plate aggregation, subduction and collision. This constitutes a movement of the building material system of continuous metabolism, or the construction of intra-regional power system.
