【摘要】 与非平衡热力学相对应的相图理论是一个空白的新领域.在激活的低压条件下,金刚石气相稳定生长的同时石墨会被腐蚀.这是近二、三十年来国际上的一个热力学难题,甚至被认为是"热力学的悖论".用非平衡定态相图的新概念可以给予很好的解说.本文对其理论基础及其计算方法作了推导和讨论.计算结果与文献报道的大量实验数据定量化地相符.更多还原

【Abstract】 The continuous diamond growth with the spontaneous graphite etching takes place under activated low prcssure conditions.The difficult thermodynamic problem had even been considered as a"thermodynamic paradox".A new concept of phase diagram of stationary non-equilibrium states has been deduced from nonequilibrium thermodynamics.It provides an excellent explanation on it.Theoretical results agree quantitatively with a lot of experimental data reported in the literature.更多还原
