Abstract：
Based on the nontopological soliton model,a new picture for deconfinement transition is given.The relation between the existence of soliton solution and the nonlinearity of potential function is analysed.The effective potential and the equation satisfied by its extreme points are given at finite temperature.It turns out that,at critical temperature T_c,the physical vacuum is transformed into perturbative vacuum,soliton solution disappears and deconfinement phase transition occurs.
