摘　　要：核-幔边界是地球内部反差最大的一个边界，也是最重要的边界。界区的核-幔相互作用过程在整个地球动力学系统中起着重要的作用。本文在概述了核-幔边界基本特征的基础上，系统地总结了有关核幔物质的化学反应和D”层的形成、核-幔间的质量传递和热量传递及其对地幔对流之贡献、核-幔耦合与动量传递等方面的研究成果及有关问题。The core-mantle boundary (CMB ) is the greatest contrasting and the most important boundary in the interior of Earth, where core-mantle interactions have been playing an important role in earth's geodynamics system. On the basis of outlining the basic features of CMB, this paper presents systematical summaries of the research results and related problems on the following aspects:the material chemical reactions and forming of D' layer, mass transfer between core and mantle; heat transfer from core to mantle and their contribution to mantle convection; and core-mantle coupling and angular momentum transferring.
