本文研究托尔曼-邦迪尘埃云非均匀引力坍缩的裸奇点的发生和性质。结果表明，裸奇点的形式在一个广泛的类坍缩模型的坍缩云的中心，其中包括Eardley和Smarr和Christodoulou考虑的早期情况。这个类还包含自相似和非自相似模型。这个奇异性的结构和强度进行检查，并调查的问题，当一个非零的措施集nonspacelike轨迹可以从奇点发出，而不是孤立的轨迹出来
We investigate here the occurrence and nature of a naked singularity for the inhomogeneous gravitational collapse of Tolman-Bondi dust clouds. It is shown that the naked singularities form at the center of the collapsing cloud in a wide class of collapse models, which includes the earlier cases considered by Eardley and Smarr and Christodoulou. This class also contains self-similar as well as non-self-similar models. The structure and strength of this singularity are examined, and the question is investigated as to when a nonzero measure set of nonspacelike trajectories could be emitted from the singularity, as opposed to isolated trajectories coming out
