Abstract: By using the method of Chapman analysis in the lattice Boltzmann model, we gave the general forms of a series of partial differential equations and Chapman polynomials. By solving the equilibrium distribution functions for complex GinzburgLandau equation, we gave the expressions of distribution functions on different time scales, and then obtained analysis solutions of  the lattice Boltzmann for complex GinzburgLandau equation.

Key words: lattice Boltzmann model, complex GinzburgLandau equation, analysis solution
