地球内部的奥秘周俊本世纪以来，人类通过利用地震波对地球内部组成和结构的探索研究，已建立起我们所熟知的蛋式或称葱皮图式圈层结构模式。近些年来，地球物理学家和地质学家们又通过应用超大型计算机处理世界各地地震观测站（约３０００个）提供的及由实验室得出的地震... The mystery of the Earth’s interior Zhou Jun Since the beginning of this century, mankind has explored and explored the composition and structure of the earth by using seismic waves and has established a well-known pattern of egg or onion pattern layers. In recent years, geophysicists and geologists, in turn, have used the very large computers to process earthquake-induced earthquakes provided by seismic stations around the world (about 3,000).
