一般非平衡定态相变系统的普适类及临界指数

UNIVERSAL CATEGORIES AND CRITICAL EXPONENTS IN GENERAL NONEQUILIBRIUM STATIONARY STATE PHASE TRANSITION SYSTEMS

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 4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 .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 .

On the basis of nonequilibrium phase transition standardized model which has universal significance,the critical singularities and scalingable peculiarities of general nonequilibrium steady state phase transition are discussed.A group of universal critical exponent relations and universal categories are derived,and the four groups of critical exponents of nonequilibrium universal categories which are calculated from it coincide well with the results of tests or theories known at present.The critical relation and universality between equilibrium systems and nonequilibrium ones 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 both theories can be integrated in the same system.
