bed roughness 例句

英汉例句

  • the presence of submerged plants increased the flow gradient, hence the bed roughness became larger to resist flow.

    淹没植物的存在起阻流作用，增大了水流的坡降，使床面糙率变大。

  • the bed roughness height was expressed by the corrective height of vegetations, and the non-uniformity roughness was expressed by the variance of the height.

    以植物高度表示有植物床面的粗糙突起程度，以高度的方差表示粗糙度的非均匀性。

  • the amount of the departure may not necessarily be large, but it results in the larger errors when the profiles are used to calculate the bed roughness length and shear stress.

    虽然偏离值可能不大，但利用对数剖面去计算河底粗糙长度和剪切应力时会引起较大的误差。

  • flow structure and the changes of bed roughness under the conditions of submerged plants in a uniform open flume with fixed-bed are experimentally studied.

    在定床条件下，主要研究了明渠内淹没植物条件下二维恒定均匀水流特性及床面糙率的变化规律。
