摘要
我们证明具有终端奇点的弱 -Fano -折具有无阻碍形变。利用这一结果并计算终端奇点的一些不变量，我们给出了关于弱 -Fano -折整体形变的两个结果。我们还处理了 -Fano -折形变无阻碍性的栈证明。

21 pages. Added several propositions about infinitesimal deformations. Deleted a section about a bound of singularities on a Q-Fano 3-fold. Instead, added a new section on Q-smoothability of a weak Q-Fano 3-fold
