摘要：
We revisit the gravitational collapse of spherically symmetric Lemaitre-Tolman-Bondi dust models. A sufficient condition for global visibility of singularity is given. This condition also allows us to extend the condition of local visibility to mass functions which are not Taylor expandable near the center.
