Also, we discuss the displacement of the steady state of the medium based on the theory of secondorderphasetransition, and study the affect to the entanglement in detail.
在二阶相变理论基础上，分析了介质稳态的移动，详细讨论了介质非零稳态的出现对纠缠的影响。

The results show that the laser process in different conditions possesses the characteristics of the first order or the secondorderphasetransition. Laser is a typical non-equilibrium phenomenon.
