单词	complexity
释义	complexity The levels of self-organization of a system. In physical systems, complexity is associated with broken symmetry and the ability of a system to have different states between which it can make phase transitions. It is also associated with having coherence in space over a long range. Examples of complexity include superconductivity, superfluidity, lasers, and ordered phases that arise when a system is driven far from thermal equilibrium (see Bénard cell). It is not necessary for a system to have a large number of degrees of freedom in order for complexity to occur. The study of complexity is greatly aided by computers in systems that cannot be described analytically. Argand diagram
