In this paper, Subalpine conifer forest ecological system was brief introduced, and their non-equilibrium problems were discussed at the level of population, community and ecological system.

In the article,the features on opening and non-equilibrium of the information-system of university were researched,the role of fluctuation for self-organization evolution of the system was revealed,the process and direction of self-organization evolution of the system were approached with reality on the basis of the self-organization theory.

This paper systematically analyzes the openness,non-equilibrium,non-linear,the process of self-organizing and nonlinear dynamics of agroecosystem,to provide theoretical basis for the regulation and control of agroecosystem,as agroecosystem is of dissipation structure.

In this paper, we discuss the theoretical system model of the "Yin Yang and Five Elements" in Chinese Medicine and analyses the balance character of this model as well as the logical generating process.

Another formula for calculation sub-flow rate of dense medium suspension is derived based the principle of balance of non-magnetic material in circulating medium.
