例句与用法

  • In the second part , we investigate the compact submanifolds m with the parallel isoperimetric section in the real space forms rm ( c ) and prove that if there exists a parallel isoperimetric section on m , and the sectional curvature of m is always greater than zero , then m is contained in a hyper - sphere ; and get that the gauss curvature of the compact surfaces m with constant mean curvature in constant curvature space r4 ( c ) is always greater than zero , then m is a totally geodesic surface or a sphere , where an isoperimetric on m means a unit normal vector field defined globally on m with m1 ( ) = constant
    ( 2 )研究了实空间形式r ~ m ( c )中具有平行等参截面的紧致子流形m ,证明了具有一平行等参截面的子流形m ,如果m的截面曲率恒正,则m包含在r ~ m ( c )的一个超球面内;对于常曲率空间及r ~ 4 ( c )中具有常平均曲率的紧致曲面m ,如果m的高斯曲率处处大于零,则m或为r ~ m ( c )中的全测地曲面或为一球面。这里m上的等参截面是m上整体定义的单位法向量场,使得m关于它的平均曲率m _ 1 ( )是常数。
  • The solutions include : the unit normal vector of the elastic - plastic boundary near the crack line , the elastic - plastic stress fields near crack line , law that the length of the plastic zone along the crack line is varied with an external loads , the maximum lengths of the plastic zone , the bearing capacity of a finite plate with an eccentric crack loaded by shear forces
    这个解包括:裂纹线附近弹塑性边界上的单位法向矢量,裂纹线附近的弹塑性解析解、最大塑性区长度、裂纹线上的塑性区长度随荷载的变化规律及其承载力。
