Combined with CAD software development of grids,the design method of bolt-sphere joint is put forward based on geometry restriction and intensity restriction. The geomitry dimension of each component is determined firstly based on bolt diameter and contexture, then, maximal pull and stress of diversitied bolt are given after intensity restriction of all components is taken into acount.

In this paper we define the concept of Projective Blaschke manifolds and extend the theory of equiaffine differential geometry to the projective Blaschke manifolds. We prved that if M be a complete projective Blaschke n-sphere and its universal covering manifold is isometric to a complete (n+1) dimensional parabolic, elliptic or hyperbolic affine hypersphere, then M is a quotient space of E^n, S^n or D^n by a isometric subgroup of its corresponding spaces.

在这篇文章中我们定义了射影Blaschke流形的概念，将等仿射微分几何的理论推广到了射影Blaschke流形，并证明：如果n维完备射影Blaschke 超球面 M 的通用覆盖流形分别是完备的抛物型、椭圆型或双曲型仿射球，则M分别是n维欧氏空间、n维超球面或n维单位圆盘关于各自空间的一个等距离散子群的商，从而对完备射影Blaschke 超球面进行了分类。

You know of course that the volume of a sphere goes up as the cube of its radius-according to normal Euclidean geometry ?
