研究了在含有宇宙(学)常数的Friedmann-Robertson-Walker宇宙模型中，充满、满足p=(γ-1)ρ物质宇宙的稳定性.通过计算引力波的扰动，以及dp/dp=γ-1的扰动，得到对于ε=-1,Λ<0，满足Einstein场方程的宇宙只要γ≥0是不稳定的.

The stability of the universe filled with matter,which satisfies P=(γ-1)ρ,is investigated in Friedmann-Robertson-Walker the universe model containing a cosmological constant.The universe satisfying Einstein field equation is obtained for ε=-1 and Λ<0.When γ≥0,the universe is shown to be unstable by calculating the perturbation of gravitational wave and using the relation dP/dρ=γ-1.
