摘    要:在具有普适意义的非平衡相变临界规格化模型基础上,讨论了一般自组织系统中的非平衡定态跃迁相变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变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变临界标度理论的理论极限而统一在同一理论体系中。

关 键 词:自组织系统  非平衡相变  临界指数  标度律  普适性  临界规格化模型  临界奇异性

Abstract:On the basis of nonequilibrium phase transition standardized model which has universal significance, we have discussed the critical singularities and scalingable peculiarities of general nonequilibrium steady state phase transition in general self-organized systems. A group of universal critical exponent relations and universal categories are derived, and the four groups of critical exponents of nonequilibrium universal categories that 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 nonequilibrium systems and equilibrium systems are also discussed. The results of equilibrium phase transition critical scaling theory are regarded as the theoretical limit of nonequilibrium phase transition critical scaling theory, and both theories can be integrated into the same system.
Keywords:nonequilibrium phase transition  self-organized system  critical peculiarity  scaling law  universality  criticalexponent
