设n >= 2是一个整数，P = diag（-In-K，I-k，-In-k，I-k）对某个整数kappa是[0，n]中的元素，R-2n的Sigma子集是一个部分对称紧凸超曲面，即，x是Sigma的一个元素，意味着P-x是Sigma的一个元素，并且（r，R）-pinched。本文证明了当R/r = a}时，对任意a是R的元素.
Let n >= 2 be an integer, P = diag(-In-K, I-k, -In-k, I-k) for some integer kappa is an element of [0, n], and let Sigma subset of R-2n be a partially symmetric compact convex hypersurface, i.e., x is an element of Sigma implies P-x is an element of Sigma, and (r, R)-pinched. In this paper, we prove that when R/r = a} for any a is an element of R.
