| 摘 要： | 该文用非平衡热力学耦合模型计算了不同温度和压力范围的金刚石气相生长Ｃ－Ｈ－Ｏ三元非平衡定态投影相图，以及固定压力下对应于４００Ｋ、６００Ｋ、８００Ｋ和１０００Ｋ的等温截面相图，探讨了温度和压力对相图中金刚石生长区边界的影响．计算结果表明，金刚石生长区随温度的升高总体上将围绕其重心按逆时针方向逐渐转动，同时生长区的形状也会有大的变化．

| Abstract: | Based on the non equilibrium thermodynamic coupling model, the ternary C H O stationary non equilibrium states phase diagrams are calculated under different temperature and pressure in this paper. The calculated results of the isothermal sections show that the whole diamond growth region will gradually rotate anti clockwise around its core with the substrate temperature increasing while its shape changes greatly. |
