肋间距 meaning in Chinese
spacing of ribs
Examples
- The channel of t / p = 0 . 5 shows the best heat transfer characteristics , and t / e = 0 . 3 gives the the best heat transfer characteristics . especially , the 45 / 45 channel could obtain more obvious heat transfer enhancement than 45 ? 60 ? channel
粗糙肋的宽度与肋间距之比t / p ，肋宽与肋高之比t / e对通道换热均有一定影响。 - The experimental results of air heat transfer show that the relative fin height , relative fin width , relative fin pitch and density of 3 - d ift with staggered arrangement fins all have an effect on heat transfer and flow friction . especially , the effect of fin density is bigger
空气换热实验的结果表明：肋叉排三维内肋管的相对肋高、相对肋宽、相对肋间距以及肋密度均对其对流换热特性有影响，其中肋密度的影响较大。 - The experimental model is a rectangular section of 15 . 2 187mm ~ 2 , which is composed of two aluminum plates . the angles between the internal netted rib turbulators and the flow direction are 45 ? for the one plate and 60 ? for the other , or both 45 ? for two plates . in the experiment , the re numbers changes from 0 . 4 10 ~ 4 1 . 5 10 ~ 5 , rib width - to - pitch are 0 . 25 , 0 . 3 and 0 . 5 , rib width - to - height are 0 . 25 , 0 . 3 and 0 . 5 , the rib height - to - hydraulic diameter ratio is 0 . 246
主要研究了在通道进口截面积(即无肋处的截面积) a为15 . 2 187mm ~ 2 、肋高与通道当量直径之比e / de等于0 . 246 ，实验雷诺数范围在0 . 4 10 ~ 4 1 . 5 10 ~ 5之间的情况下，雷诺数re 、肋向角a 、肋宽与肋高之比t / e和肋宽与肋间距之比t / p等参数对通道强化传热与流动阻力特性的影响。 - Because they are two - - way ribbed and with re1ative1y smal1 rib spacing , reinforced concrete waff1 e s1abs exhi b it higher st if fness and smaller deflections and behave we11 under 1oads . because of their architectura1 benefits for 1ower structura1 height and l ight weight as we1l as economic benefits , they are best suited for 1arge span structures as wel1 as tal1 bui1dings
钢筋混凝土双向密肋楼盖由于两向带肋，肋间距较小，因此不但受力性能好，而且刚度大，整体性好，变形小，结构自身高度小，材料省，自重轻，经济性好，特别适合于在跨度较大的多层和高层建筑楼盖中采用。 - 4 . as for the design of this kind of structure mentioned above , the thesis " ana1yzed " systematica1ly the inf1uence of the over1ay of the two - - way reinforcement on its u1timate . 1oad capacity , the deciding of such important factors as the depth - - span ratio and the rib spacing etc
针对周边支承双向密肋夹心楼盖的设计，本文结合实例，较为系统地分析了两向钢筋重叠对楼盖极限承载力的影响以及楼盖高跨比、肋间距等参数的取值等问题，为该类楼盖的设计提供参考。
