This study reports the cross-sectional curvature effect resulted from a twisted tape fabrication or installation into an annular pipe on the enhancement of heat transfer to pay attention to the use of twisted tapes more efficiently. Six different twisted tapes having two twist ratios (3 and 4) ...
On pinching problem of sectional curvature on minimal submanifolds in a symmetric space; 局部对称黎曼流形中极小子流形的截面曲率的pinching问题 2. Let Mmbe a compact submanifold with positive sectional curvature of a space form Nn(c). 设Mm是空间形式Nn(c)中具有正截面曲率的紧致子流形,证明了如果...

To improve the cross-sectional shapes (outer curvature, wall thickness change) of the comer zones of hexagonal steel pipes (168.0, 170.0 and 173.0 mm wide, STK400) formed by an extroll-forming mill, an expanding-type forming tool with six idler rolls is introduced into the groove of No. ...
For example, the validity of the complete expansions for the beams with abruptly changing cross-sectional curvature is not a priori obvious because of the presence of a new small scale—the curvature radius that is much smaller than the transversal size of the beam. Our task here is to ...
Then local curvature features at different smoothing levels were iteratively introduced into the registration algorithm to better match the small and local geometric structures of the individual mesh to the atlas. The individual thickness values were then mapped from the image onto the mesh surface and...
The effect of macroscopic characteristics of the hair fibers, such as fiber diameter, cross-sectional shape, and curvature on luster is demonstrated. ... K Keis,KR Ramaprasad,YK Kamath - 《International Journal of Cosmetic Science》 被引量: 33发表: 2010年 A comparative cross-sectional study ...
and rectangular cross-sectional shapes because the circular cross section is heated uniformly around the whole cross section. Accordingly, it is easy to understand that the lower fire resistance of square cross-sectional columns is attributed to the fact that the square cross-section corners are heat...
