The characterization of moebius sectional curvature in unit sphere
截曲率的內蘊性 -
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 ）研究了實空間形式r ~ m （ c ）中具有平行等參截面的緊致子流形m ，證明了具有一平行等參截面的子流形m ，如果m的截面曲率恆正，則m包含在r ~ m （ c ）的一個超球面內；對于常曲率空間及r ~ 4 （ c ）中具有常平均曲率的緊致曲面m ，如果m的高斯曲率處處大於零，則m或為r ~ m （ c ）中的全測地曲面或為一球面。這里m上的等參截面是m上整體定義的單位法向量場，使得m關於它的平均曲率m _ 1 （ ）是常數。 -
Three kinds of steel sphere and the backing sheet matching schemes have been put forward in this article according to the different circumstances. the matching schemes are studied in detail by inner mongolia hai bowan power plant ( 100mw unit ) and feng zhen power plant ( 200mw unit ). and the suitable matching schemes are selected for two plants
並且分別以內蒙古海勃灣發電廠（ 100mw機組）和內蒙古豐鎮發電廠（ 200mw機組）為例，對上述三種方案和近年來我國火力發電廠普遍採用的幾種方案進行了較為詳細的探討，經過技術經濟分析和比較，為以上兩個發電廠確定了經濟合理的鋼球和襯板匹配方案。 -
