在本文中，我们考虑球对称度量的奇异性的形式指定的是“幂律型”。这一族包括所有托尔曼-邦迪尘埃坍缩，但假设的形式要普遍得多。我们计算了奇异性附近能量-应力张量的渐进行为，并表明即使奇异性是局部裸的，也有可能满足主导能量条件。这似乎与强宇宙审查假说相矛盾。然而，它表明，如果奇异性不是壳十字，那么能量应力张量是渐近极值（|P r|阿普尔|P|或其中一个压力为负（P r < 0或P r < 0）
In this paper we consider spherically symmetric metrics having singularities of a form designated an being «of the power-law type.» Included in this clans are all Tolman-Bondi dust collapses, but the form postulated is very much more general. We calculate the asymptotic behavior of the energy-stress tensor near the singularity, and show that it is possible to satisfy the dominant energy condition, even when the singularity is locally naked. This seems to contradict the strong cosmic censorship hypothesis. However it is shown that if the singularity is not a shell cross, then the energy-stress tensor is asymptotically extreme (|P r | ≃ ρ or |P ⊥| ≃ ρ) or one of the pressures is negative (P r < 0 or P ⊥ < 0)
