unit normal vector造句
例句與造句
- 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(shí)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的截面曲率恒正，則m包含在r ~ m ( c )的一個(gè)超球面內(nèi)；對(duì)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的高斯曲率處處大于零，則m或?yàn)閞 ~ m ( c )中的全測(cè)地曲面或?yàn)橐磺蛎?。這里m上的等參截面是m上整體定義的單位法向量場(chǎng)，使得m關(guān)于它的平均曲率m _ 1 ( )是常數(shù)。 - 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
這個(gè)解包括：裂紋線附近彈塑性邊界上的單位法向矢量，裂紋線附近的彈塑性解析解、最大塑性區(qū)長(zhǎng)度、裂紋線上的塑性區(qū)長(zhǎng)度隨荷載的變化規(guī)律及其承載力。 - It's difficult to find unit normal vector in a sentence. 用unit normal vector造句挺難的
