duct loss 解釋
管道阻力損失
  • duct : n. 1. 管,導管,輸送管;槽,溝,渠道。2. 【無線電】波道;【電學】(電線,電纜等的)管道。
  • loss : n. 1. 喪失;丟失,遺失。2. 減損,損失,虧損(額);損耗;減少,下降。3. 失敗;輸掉。4. 錯過;浪費。5. 損毀;【軍事】傷亡;〈pl. 〉 傷亡及被俘人數。
  1. In the situation that the reflection loss of the duct inwall was not in considering, even condensed the pump beam 100 times, it could realize the output efficiency of more than 70 %, this was that the other coupling way hardly to accomplish

    在不考慮內壁反射損耗的情況下,即使將泵浦光束縮束100倍,也能夠實現70 %以上的輸出效率,這是現有其他耦合方式難以實現的。

  3. Firstly, working theory and structure of concrete pump are lucubrated. and the flowing state of the concrete in duct is analyzed by virtue of the rheology theory. secondly, the flowing model of concrete in duct is established, with that, the pressure loss of concrete flowing in duct is analyzed, too

    論文首先對混凝土泵的工作原理和結構進行了綜合分析;基於流變學原理,深入分析了泵送混凝土在輸送管中的流動狀態,建立了混凝土在管道中的流動模型,分析了混凝土在管道中流動的壓力損失;基於運動學和動力學基本原理,對混凝土s管閥的運動學和動力學進行了分析。
  4. At first, the soft of bridge structure, gqjs, is used to calculate the structure of prestressed concrete continuous beam bridge and the deformation and stress of the concrete box beam are given out ; then by measuring and analyzing the datum of the stress in the prestressed steel rope and the stress of section in the concrete box beam, this article presents two ways to identify the reasonable friction deviation factor k between longitudinal prestressed tendons and the wall of duct ( indirectly and directly ), and discover the regular pattern of prestressed friction loss

    首先運用橋梁結構分析專用軟體gqjs對預應力混凝土連續梁橋進行結構計算,得到了各施工工況下混凝土箱梁的撓度和截面應力;然後給出了識別引起結構預應力損失的孔道偏差系數k的兩種方法(間接法和直接法) 。通過對測得的預應力索沿程應力和混凝土箱梁截面應力數據的分析處理,得到了合理的預應力孔道摩擦偏差系數及預應力摩阻損失規律。
