【Abstract】 The stability of a kind of cosmological models is given. The variations of the cosmological model for parameters λ and k were discussed respectively. Near λ =0, the cosmological model is unstable with the change of λ , and near λ=β=0 , the cosmological model is unstable with the change of k . So when we consider the stable cosmological model, we must consider the no zero cosmological constant.更多还原
