摘要The stability of the Cauchy horizons is investigated in two-dimensional (2D) dilaton black holes possessing multihorizon structures. For the Cauchy horizon with nonvanishing surface gravity, the Cauchy horizon will be converted into a nonscalar curvature singularity under the perturbation of the purely infalling null dust, and a scalar curvature singularity will be formed at the Cauchy horizon when the 2D dilaton black holes are perturbed by both outgoing and infalling null dust. For the Cauchy horizon with vanishing surface gravity, we find that the Cauchy horizon can be completely stable when p greater than or equal to 1 + 2/b, and mass inflation can take place only if p < 1 + 1/b, but a scalar curvature singularity will still be formed along the Cauchy horizon when 1 + 1/b less than or equal to p < 1 + 2/b, where the constant p comes from the infalling radiation with the power-law tail upsilon(-p-1), and b means that the equation determining the horizons has b + 1 degenerate roots at the Cauchy horizon. When quantum effects are considered, the classical stable Cauchy horizon is still quantum mechanically unstable and is converted into a scalar curvature singularity. In addition, this paper can also be acted as a further test of the Cauchy-horizon stability conjecture suggested recently by Helliwell and Konkowski.
