摘　　要：对地层褶皱、大山脉形成及海陆起源给出动力学解释,是地球科学的核心问题。从冷缩说、大陆漂移说到板块理论创立,何种力量驱动始终是理论的难点。从地槽活动现象规律,找到构造运动源于地壳深部壳幔物质的相向、协同大尺度水平迁移。日月引力产生交变固体潮汐应力,引起壳、幔圈层相互剪切。因“剪切运动不稳定性”,潮汐应力转化出驱动莫霍面两侧壳、幔物质水平相向迁移的驱动力Fc,使莫霍面波动形成地球上最大的内波系统。其中蕴藏的重力势能,足够全球大地构造运动所需,能量来自地球转动能消耗。有限元数值模拟,实现了幅度万米的地槽沉降及两侧地带隆升,揭开了地槽活动之谜。“内波说”对全球洋中脊体系、陆壳双层结构、大陆溢流玄武岩和洋底火山四种全球性大地构造现象给出成因解释。大陆起源是全球构造理论核心问题。“内波说”揭示的“薄地壳底部物质自动向厚地壳底部迁移”的地壳增厚机制,将海岛生长成人类赖以生存的大陆。根据“大陆根”等现象,“内波说”支持大陆固定说。全球构造运动的发展方向是:洋中小岛合并成陆地,陆壳不断扩大,洋壳不断缩小,最终像月球那样成为陆壳为主、构造运动停止的星球。“内波说”不是“板块说”的改进。从理论建立出发点、出发地域、依赖的主导能源、物质运动形态、地质史长度方面,两者均不相同。这是两种不同思路的学术体系。It is the core issue of earth science to give kinetic interpretation of formation folds, formation of large mountains and the origin of land and sea. From the theory of cold shrinking, the drift of the mainland to the establishment of the theory of the plate, what kind of power drive is always a difficult point of theory. From the law of the movement phenomenon of the trough, the tectonic movement originated from the opposite direction and coordinated large-scale horizontal migra-tion of the crust material in the deep crust. The gravitational pull of the sun and the moon pro-duces alternating tidal stress, causing the shell and the ring to shear each other. Due to the “shear motion instability”, the tidal stress transforms the driving force Fc that drives the shells on both sides of the Moho surface and the horizontal migration of the bismuth material, causing the Moho surface to fluctuate to form the largest internal wave system on the earth. The gravitational potential energy contained therein is sufficient for the global tectonic movement, and the energy comes from the rotational energy consumption of the earth. The finite element numerical simulation realized the settlement of the ground trough with a width of 10,000 meters and the uplift of the two sides, which uncovered the mystery of the trough activity. “Internal wave theory” gives a genetic explanation for the four global tectonic phenomena of the global mid-ocean ridge system, continental crust double-layer structure, continental overflow basalt and oceanic volcano. The origin of the continent is the core issue of global tectonic theory. The “Civil Wave” reveals the crustal thickening mechanism of “the thin crustal bottom material automatically migrates to the bottom of the thick crust”, which grows the island into a continent on which humans depend. According to the “continental roots” and other phenomena, “internal wave theory” supports the mainland fixed theory. The development direction of the global tectonic movement is: the
