光学多稳系统的相变及临界点分类

参照朗道相变理的基本精神，确定光学多稳性系统的相变与临床界现象，揭示了相变的多样性，以及多稳系统通向完全单稳状态态的不同路径。多稳性的级次愈高，相变的式样也就愈多。

Phase Transitions in the Multi-Stability Optical Systems and the Classification of Critical Points

Referring to the principle of Landau′s theory on phase transitions, the varied transitions and critical phenomena in multi-stable optical systems are discussed. It is demonstrated that the higher the order of the multi-stability, the more varity of transitions, and shown also that the multi-stable system possesses different routes to complete mono-stability. A classification scheme of critical points corresponding to some transitions or bifurcation is made according to the stability criterion. This classification is useful to the study of critical phenomena, especially in non-equilibrium systems including the multi-stable systems.
