【摘要】 本文依据现有地球物理资料,研究了在我国不同地区的上地幔低阻层和低速层埋深和分布特征,讨论了它们的形成及与热流值变化的关系,同时还与苏联萨哈林岛、西伯利亚地台、捷克及欧洲中部喀尔巴仟山地区以及中国有关地区进行了对比,指出了它们与地震波传播过程中能量吸收间的关系.更多还原

【Abstract】 Based on the research of surface wave and body wave of natural earthquakes,detection of artificial explosion seismics and geomagneto-teluric deep sounding carried out in recent years, this paper suggests a low resistivity and low velocity layer and discusses the structures of the upper mantle at East China and part of West China.What was obtained all over the country indicates that in the whole the low velocity layer and low resistivity layerof the upper mantle are in accordance with each other and that both of them have the same mechanism and genesis.更多还原
