upstream water level
基本解釋
- 上游水位
英漢例句
- At the same time, by the upstream water level raising, The water area and wind wave of the reservoir have increased.
同時(shí)，樞紐上游水位的提升也增加了庫(kù)區(qū)的水面寬度和水域面積，致使庫(kù)區(qū)風(fēng)浪規(guī)模擴(kuò)大； - With the upstream water level reducing and the downstream water level increasing, the highest tangent velocity also moving to the pipe center.
隨上游水位的降低及下游水位的升高，切向流速最大值點(diǎn)也不斷向管中心一側(cè)移動(dòng)。 - The bigger the downstream water level, the outstanding of variation degree of axial velocity along radius distribution when upstream water level is same.
下游水位越高，變化相同的上游水位時(shí)，軸向流速沿徑向分布的變化程度越大。
