我们分类del Pezzo表面的商奇点和皮卡德秩1承认Q-Gorenstein光滑。这些表面出现的奇异纤维的德尔佩佐纤维在3倍的最小模型程序，也在模量问题。
We classify del Pezzo surfaces with quotient singularities and Picard rank one which admit a Q-Gorenstein smoothing. These surfaces arise as singular fibres of del Pezzo fibrations in the 3-fold minimal model program and also in moduli problems.
