用定量缺陷化学方法计算了含Fe的MgSiO{sub 3}钙钛矿中点缺陷的平衡浓度。缺陷浓度对温度，氧活性，和压力的依赖关系示出。这些计算表明，在控制实验条件的差异，可以导致显着差异的点缺陷控制性能。
Equilibrium concentrations of point defects in Fe-bearing MgSiO{sub 3} perovskite are calculated using a quantitative defect chemistry approach. Dependences of defect concentrations on temperature, oxygen activity, and pressure are illustrated. These calculations demonstrate how differences in the control of experimental conditions can lead to significant differences in point defect-controlled properties.
