| 摘 要： | 核磁共振（ＮＭＲ）波谱技术的应用极大地促进了对熔体结构的研究，获得了巨大的成就，主要表现在以下几个方面：成网离子在熔体结构中的分布特征；桥氧和非桥氧的有序－无序特征以及非桥氧环境的变化与熔体结构的关系；变网离子在熔体中的结构意义及地位；键角与键长的分布特征；温度对非桥氧环境的制约关系等。ＮＭＲ技术的发展使对熔体结构有序化机制的研究终于成为可能。

| Abstract: | The development of NMR technology has enabled us to get a new picture of many petrological problems,including the relationship between the physical properties of magma (i.e.density,viscosity,and relaxation of melt structure) and the volatiles (their types and/ or contents),and the reacting mechanism of water with silicate melts.This paper reviews the progress in the research of melt structures in the following aspects:the order-disorder characteristics of the distribution of bridge and nonbridge oxygens in melt structures;the distribution of the bridge length and bridge angle in melt structures;and the distribution characteristics of the network-forming elements;the dynamical property of melt structures. |
