介绍建立大地构造内波假说的根据，即：（１）全球海陆分布的低阶球谐特征；（２）全球大洋中脊体系的存在；（３）大陆永存及生长的事实；（４）地壳均衡及莫霍面的化学分界面性质；（５）地槽活动的现象、规律等。在分析以在事实的基础上，研究了大地构造运动中主要的物质运动过程，认为从薄地壳底部向厚地壳底部迁移的地壳物质流，引起地壳厚度的自激波动，推动地槽运动和大陆生长。
(1) The low-order spherical harmonic features of the global land-sea distribution; (2) The existence of the global mid-ocean ridge system; (3) The fact that the continent is eternal and growing; (4) The crust Equilibrium and Moho surface chemical interface properties; (5) the activities of the earth’s surface phenomena, laws and so on. In the analysis, based on the fact, the main material movement in the tectonic movement of the earth was studied. It is believed that the crustal material flow that migrated from the bottom of thin crust to the bottom of thick crust caused self-excitation fluctuation of crustal thickness and promoted the movement of the earth’s trough and the continent Grow.
