突现、分层与对称性破缺

20世纪40年代以来，复杂性系统科学的研究，揭示出从无机的物质世界到有机的生命世界，再到复杂的社会经济生活，都是从无序走向有序，而对称性破缺是系统走向有序的重要机制。突现与分层是对称性破缺的表现形式；物质系统在分层的过程中“涌现”出一些新质，并使物质系统的丰度和结合度呈递减状态。本文通过对非线性、突现、分层等现象的考察，指出每一次对称破缺都可能有新质的突现，从而使自然系统的层次结构跃上一个新的台阶。

Emergence, hierarchy and symmetry breaking

Since the 1940's,the study of complex system science shows out that from inorganic material world to organic life world even to the complex social economical world are all of the process of from disorder to order,with which the main dynamical cause is symmetry breaking.Emergence and hierarchy is the manifestation of the symmetry breaking.The material system "emerge" some new quality,which leading to the descent state of abundance and combination degree.The paper studies the phenomenon of non-linearity,emergence,hierarchy and so on,pointing out that every symmetry breaking has the possibility of the new quality's emergence,resulting in a new stage of the natural system's hierarchy structure.
