ring section
Examples
- The general failure expression on reinforced concrete members with annular section
钢筋混凝土环形截面构件破坏的统一表达 - Calculation of bended structural member reinforcement of rectangular section of reinforced concrete
环形截面偏压构件非均匀配筋承载力计算 - Employing perturbation method and numerical simulation , we study the flow in rotating helical pipes including different rotations , different cross sections ( circular , elliptical , annular and square cross section ) , and different geometrical structures
采用摄动方法和数值计算方法，研究了处于多种旋转状态下、多种截面形状(圆截面、椭圆截面、环形截面、矩形截面) 、不同几何结构旋转螺旋管道流动。 - ( 5 ) as torsion is increased , the anticlockwise secondary vortexes and the negative area of the stream function increase ; the axial velocity moves anticlockwise ( annular pipe ) or clockwise ( circular pipe ) ; the friction factor ratio finally reaches the value about 1
( 5 )增大挠率，逆时针方向旋转的一二次涡和流函数的负值区域增大，轴向速度最大值的位置按逆时针（环形截面）或顺时针（圆截面）方向旋转，摩擦系数比最终趋向于1 。 - When f is about fr , for curved pipes , the secondary flow appears eight vortexes for annular cross section and four for circular and four or six for elliptical ; for helical pipe , the secondary flow appears as a loop flow for annular and circular cross section , and a saddle flow for elliptical cross section
当f在fr左右时，对于弯管，环形截面上存在八个涡，圆截面上存在四个涡，椭圆截面上存在四个或六个涡；对于螺旋管，圆截面和环形截面上二次流表现为环流，椭圆截面上表现为鞍流。
