对于在[r]（即r维空间）中一个代数曲面的孤立奇点，我的意思是这样一种奇点：它不仅不在该曲面的多重曲线的任何分支上，而且还具有如下性质：当该曲面从一个一般的[r - 4]空间投影到[3]空间时，这个奇点仍然是孤立的，也就是说，由投影所产生的双曲线的任何分支都不一定会经过它。
By an isolated singularity of an algebraic surface in [r] (i.e. space of r dimensions) I shall mean one which not merely is not upon any branch of a multiple curve of the surface, but has also the property that when the surface is projected into [3] from a general space [r − 4] the singular point remains in isolation, i.e. no branch of the double curve created by the projection will of necessity pass through it.
