equilibrium criterion
3.The stability of the helical equilibrium is analyzed with phase plane method, and an analytical criterion of stability is revealed.
4.This paper discussed the thermal equilibrium and critical condition in exothermic reaction system, and deduced the values of dynamic parameters such as the judging criterion for thermal runaway, the ignition temperature and extinction temperature in the critical state of thermal runaway when there is no consumption of reaction materials.
5.From the entropy criterion of isolated system, the balance equilibrium condition of multi-compound poly-phase system C(subscript V)>0, (The equation is abbreviated), (The equation is abbreviated) is intensively deduced, and the physical significance of the balance equilibrium condition is given and proved.
6.Abstract: According to the principle of themodynamics and the method of linear algebra,the eqiulibrium criterion and eqiulibrium condition of the complex system have leen discussed systematically.The calculation method of eqiulibrium composition of chemical reaction,phase transfer as well as simultaneous equilibrium in the complex system have been proposed.
