摘要
在具有普适意义的非平衡相交临界规格化模型基础上，讨论了一般非平衡定态跃迁相交的临界奇异性和可标度性，导出一组普适的临界指数标度关系及普适类，由之计算出的四组非平衡普适类的临界数值与目前已知的实验及理论结果吻合得非常好。本文还讨论了平衡相交与非平衡相变的临界联系及普适性，将平衡相变临界标度理论的结果作为非平衡相交临界标度理论的理论极限而统一在同一理论体系中。
On the basis of nonequilibrium phase transition standardized model which has universal significance, we discuss the critical singularities and scalingable peculiarities of general nonequilibrium steady state phase transition. A group of universal critical exponent relations and universal categories are derived, and the four group of critical exponents of nonequilibrium universalcategories which are calculated from it coincide well with the results of tests or theories known at present. In this paper, the critical relation and universality between equilibrium systems and nonequilibrium systems are also discussed. The results of equilibrium phase transition critical scaling theory are regarded as the theory limit of nonequilibrium phase transition critical scaling theory, and the both theories can be integrated in the same system.
