We introduce a diffusion-ZGB model including the diffusion of o and co for the surface catalytic reaction of O2 and co, and eliminate the second-orderphasetransition naturally.
It is proved strictly that this incommensurate phasetransition is of secondorder.
严格证明了该非公度相变是第二类的。

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.
