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结果吻合得非常好。

关 键 词:非平衡相变  临界性质  标度律  临界指数

Abstract: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.
Keywords:nonequilibrium phase transition  critical peculiarity  scaling law  uni- versality  critical exponent
