摘要：

We prove a cosmic no-hair theorem for Bianchi models in power-law inflation. Provided that the potential of an inflation phi is exp( -lambda-kappa-phi) with 0 less-than-or-equal-to lambda < square-root 2/3, we find that the isotropic power-law solution is the unique attractor for any initially expanding Bianchi-type models except type IX. For Bianchi type IX, this conclusion is also true if the initial ratio of the vacuum energy to the maximum three-curvature is larger than one half.
