摘要：

The importance of cosmological constant for the cosmological models is given. The variations of the cosmological model for parameters lambda and k were discussed respectively, Near lambda = 0, the cosmological model is unstable with the change of lambda, and near lambda = beta = 0, the cosmological model is unstable with the change of k. So when we consider the stable cosmological model, we must consider the nonzero cosmological constant.
