![]() Most of the fluctuations decay gradually (relaxation) and the system restores the original state. Fluctuations are referred to as the deviations from the statistical average value of the system variables. The internal incentives of making the system produce an orderly structure are fluctuations. Nevertheless, a qualitative change of a system evolution needs internal conditions. Openness and nonequilibrium are referred to as the external conditions of the orderly structure mainly. “Nonequilibrium is the origin of orderliness.” 3. Only when the system is far from equilibrium and in open conditions can the new stable, dynamic-orderly dissipative structure be possible to form. The state near equilibrium tends to form a nonequilibrium steady state under modest energy exchange with the external environment, but the dissipative structure can hardly occur. The equilibrium state hardly results in a dynamic orderliness on the contrary, it reflects disorderly movement. The system may be in three different states: (1) thermodynamic equilibrium state (2) near equilibrium state and (3) far from equilibrium state, that is, nonlinear nonequilibrium state. Nonequilibrium is the source of dynamic orderliness. Namely, the system must exchange matter, energy and information with the external environment constantly. The first condition for the formation and maintenance of the dissipative structure is that the system must be in the open state. The system is constrained by various parameters of its own structure and function or the external environment. The system takes evolution tendency of transformation and perfection when it is interacting with the external environment. The system has sticking capabilities to ensure the structural stability and functional stability of the system, having certain antiinterference. The system has the ability of self-organization, it can regulate automatically through feedback in order to adapt to environment changes. Without such exchanges, the occurrence and development of an open system are impossible. The system exchanges matter, energy, and information with the external environment constantly. Open system has the following characteristics: a. The system exists only in an open system. ![]() The dissipative structure in a dynamic-orderly operation would be formed in the system far from the equilibrium state under the following condition: the system must be open and far from the equilibrium state, with fluctuations and a nonlinear interaction mechanism ( Yan, 1987b). ![]()
