1) downwelling
[daun'weliŋ]
下降流
1.
Upwelling and downwelling are common in the South China Sea (SCS).
如,横越陆架的Ekman输运形成的升降流,它们有粤东沿岸上升流、海南岛东部沿岸上升流、越南东部沿岸上升流和冬季沿西边界的下降流、夏秋季沿东边界的下降流等;Ekman泵吸作用形成的上升流,有吕宋岛西北部上升流和越南东部上升流等;地形作用形成的上升流,其中有因地形变浅引发的上升流,绕岛涡旋引发的升降流,涡度守恒弓J发的升降流和岬角地形引发的升降流;以及海盆尺度环流引起的升降流和过渡季节因动力调整过程而引发的各种中尺度涡产生的升降流等。
2) air descend
气流下降
1.
A comparison experiment between the common flue-cured house with air descend and the improved close flue-cured house was conducted to investigate the flue-cures cost and economic benefit.
以原烤房为基础改成增大容量的密集烤房,采用烤烟品种云烟87为材料,对气流下降式与小型密集烤房的烘烤成本和经济效益进行了对比分析。
3) downward flow rate
下降流量
1.
Measurement of the downward flow rate at different levels inside a cyclone;
旋风除尘器下降流量的研究
4) downdraft
[英]['daundrɑ:ft] [美]['daʊn,dræft]
下降气流
1.
Methodology of avoiding condensation and downdraft in displacement ventilation plus cooling ceiling system
置换通风加冷却顶板系统避免结露和下降气流的方法
2.
Currently, displacement ventilation and cooling ceiling system (DV/CC) has two main disadvantages: first, condensation will happen when the radiant panel temperature is lower than the dew point temperature of air around it;second, the downdraft from the cooling ceiling destroys the airstream shape of DV, which reduces indoor air quality.
目前冷却顶板/置换通风系统有两个突出问题:冷却顶板易“结露”;冷却顶板形成的“下降气流”破坏了置换通风的流型,降低了空气品质。
5) drop-out current
下降电流
6) flow (rate) reduction
流量下降
