自地质学家、地球物理学家和地球化学家研究世界大洋的洋底以来,已有20多年了,在这段时间里,积累了关于各种构造(包括洋中脊、边缘海、岛孤和海沟等)的结构的丰富资料。结果,地球科学补充了新的地球动力学理论,特别是“岩石圈板块构造”理论。杨申的报告中包含了对这个理论的某些论点的批评,而哈茵则强调了它的有力的一面。杨申正确地指 It has been more than 20 years since geologists, geophysicists and geochemists have studied the ocean floor of the world’s oceans, during which time they have accumulated information on various tectonics (including mid-ocean ridges, marginal seas, And trenches, etc.) of the structure of the rich information. As a result, Earth Science complements new theories of geodynamics, especially the “lithospheric plate tectonics” theory. Yang Shen’s report contains criticisms of some of the arguments of the theory, while Hahn emphasizes its forceful side. Yang Shen refers exactly
