摘　　要：斜方辉石在地壳与上地幔的研究中具有重要的意义，本文介绍了近年来有关其M1与M2间Fe-Mg有序－无序反应的热动力学性质、高温高压结构变化及其相变、热膨胀性质、建立晶体化学模型以及空间群再确认等方面的研究进展。Orthopyroxene is of great significance in the study of the evolution of the crust and upper mantle.In recent years some progress has been made in this field, including the thermodynamic characteristics of Fe-Mg order-disorder reaction between M1 and M2 of orthopyroxene, structural changes under high temperature and high pressure, phase transition, thermal expansion, the establishment of crystalchemical models, and reconfirmation of its space group.
