摘    要：利用高平-Y.塔达方法成功地解决了石英的类质同象混晶的吉布斯生成自由能计算后,运用热力学推导了石英中类质同象点缺陷浓度和石英形成的物理化学条件间的定量关系,并得到了实验验证.从而,为有关石英的微量元素及成因研究开辟了广阔的前景,亦为利用矿物形成的物理化学场求算类质同象点缺陷浓度给出了可供借鉴的先例.

Abstract: After the Gibbs free energy of formation of isomorphic quartz crystal wassuccessfully calculated through Gao Ping-Y. Tardy method, the paper deduced therelationships, which were testified by experiments, between the physical andchemical field of quartz's formation and the concentration of point defects inquartz by using thermal dynamics. The relationships, therefore, ushered in abright prospect for researches on quartz's trace elements and its formation, andcould also provide a referential precedent for us to calculate the concentration of isomorphic point defects in any mineral by using its physical and chemical formation field.
