摘要
从一般非平密相变系统的规格化模型出发．注意到平衡相交与非手衡相变两者临界行为的差异与相似性，重点考察了两者在参考态、势函数、相关函数、可标度性、临界指数、标度律和普适性等方面的相互联系，讨论了两者的临界统一性。即平密相变临界现象可作为非平衡相变临界现象的一种特殊极限形式而含于同一理论体系中，这在一定程度上揭示了两者的临界相似根源。
Using the standardized model of the nonequilibrium phase transition systems. the relations between the equilibrium and nonequilibrium phase transitions are investigated in terme of the reference states, the patential functions, the correlation functions and the critital properties. It is shown that the critital phenomena in the equilibrium phase transitions are the special ones in the nonequilibrium phase trannsitions,which means they have the similar origins.
