论文摘要
我们在平滑立方三倍的超平面截面上计算了一些线的数值不变性。我们还证明，对于任何流畅的高度表面$ x \ subset \ mathbb p^{n+1} $ of度量$ d $在代数封闭的特征零字段上，如果$ d> n> n> n> n> 1 $和$（n，d）\ neq（2,3），（2,4），（3,4），（3,3,4）$，然后是一般超级截面，仅在许多其他部分中属于某些属于某些属于该属于的东西。
We compute some numerical invariants of the lines on hyperplane sections of a smooth cubic threefold over complex numbers. We also prove that for any smooth hypersurface $X\subset \mathbb P^{n+1}$ of degree $d$ over an algebraically closed field of characteristic zero, if $d>n>1$ and $(n,d)\neq (2,3),(3,4)$, then a general hyperplane section only admits finitely many others which are isomorphic to it.
