round sphere meaning in English

圆球

Since , then , it has a furthest limit , it is complete on every side , like the mass of a rounded sphere , equally poised from the center in every direction ; for it cannot be greater or smaller in one place than in another
然而，由于存在者有一条最后的边界，它在各方面都是完全的，好象一个滚圆的球体，从中心到每一个方面距离都相等，因为不能在哪个地方大一点或小一点。
In 1951 , h . hopf proved , by associating a holomorphic 2 - differential to each constant mean curvature surfaces in r3 , that only compact genus zero surfaces immersed in r3 with constant mean curvature are the round sphere , in chapter two , we consider the same question about the compact 2 - type surfaces of genus zero in s7
1951年， h . hopf发现r ~ 3中每个常平均曲率曲面都伴随一个全纯微分2 -形式，并证明了零亏格的常平均曲率闭曲面一定是r3中的球面.本文的第二章对于犷中零亏格的2型曲面讨论了类似的问题
