| 摘 要： | 地球内部物质组成的研究涉及对地表现象的深入解释,与地球动力学、地球热结构及宇宙演化有着密切的关系.本文综述了这方面的研究结果及近期的进展,指出两种地幔模型的主要分歧点,讨论了地幔中的主要相变及与间断面的关系,对今后研究提出四点意见.

| Abstract: | The study of composition in the Earth's interior relates to explaining thoroughly the phenonmena atthe Earth's surface,which has close relation to geodynamics,Earth's thermal regime and the cosmic evolu-tion.This paper reviewed the results of these fields,especially the developments recently,pointed out theprincipal differences of two mantle models,discussed the relation of the phase transformations with thediscontinuities,put forward 4 points of proposals for the future study. |
