桨

The agitation power consumptions in boiling systems decrease uniformly with the increase of agitation speed, whereas the relative power demand (RPD-the ratio of agitation power input of HEDT for gassed system to that for ungassed system and under the same agitation speed) can maintain at a high level for high gas loadings even when the impeller is operating with a high impeller tip speed. The gas hold-up in the boiling system is much lower than that in the cold gassed system, and the gas hold-up in boiling system increases at first and then decreases with the increase of the agitation power consumption per liquid mass P(subscript m. It implies that the boiling three-phase system has a maximum gas hold-up point. The changes of nucleation site of vapour bubble and the character of suspension of the solid particles with the rotational speed of the impeller are responsible for those behaviors mentioned.

在沸腾条件下，搅拌功率消耗随着搅拌转速的增加有所下降，但HEDT桨具有较高的载气能力，即使在高叶端线速度下，相对功率消耗仍能保持在较高的水平；沸腾体系的气含率随单位质量流体输入功率的增加表现出先增后减的规律，即存在气含率的极大值，蒸汽成核位置和固体颗粒悬浮特性随搅拌功率增加而改变是造成上述行为的主要原因；沸腾体系中的气含率远远低于常温通空气体系。

Several firms are building new factories: Vestas has just announced its first American plant, which will make blades in Colorado.

几个公司正在建造新工厂：维斯塔斯公司刚宣布了他们的第一个美国工厂，等到建成时，它会在科罗拉多州生产桨叶。

They are capable of surviving out of water, and when on land their skin secretes a gelatinous goo to retain moisture However, their large paddle feet are better suited for swimming, and waterhorse dragons tend to move very awkwardly when on land.

它们不在水里也能存活，当在陆地上时它们的皮肤会分泌一种凝胶状的粘液以保持湿润。然而它们大桨一般的脚更适合用来游泳，当在陆地上时水龙马移动得相当笨拙。

The turboprop engine is very much like the turbojet.

涡轮螺桨发动机与涡轮喷气发动机十分相似。

" Let's get a hump on," Abe said; and the two boys dipped their oars deeper into the brown water.

&快划吧，&阿贝说道。两个男孩子于是将桨深深地划进棕褐色的水里。

The cars are a good trick; but it has reached the time to play for safety.

把那两把桨放在那儿是个好计策；不过已经到了该安全行事的时候。

The oars are a good trick; but it has reached the time to play for safety.

这两个桨横在那边倒是好点子，但是在这个时候，该以安全为重。
