Venturi tube is one of key equipments in process of purification and recovery of converter gas, which is used to drop temperature of converter gas with spraying jet fixed at throat of Venturi tube.
文氏管内部的流动与传热较为复杂，不仅涉及喷淋液滴与烟气在流动过程中的相互作用，而且涉及喷淋液滴遇到高温烟气发生相变进行的传热传质。
That means that the jet can fly at a relatively high 600 to 800 feet spraying its payload as it goes, making it safer in theory, even suitable for firefighting at night.
也就是说，这架喷气式飞机可以在相对较高的600至800英尺，在飞行过程中喷洒出有效荷载，从理论上讲更加安全，甚至适合夜间扑火。
In the cold gas dynamic supersonic powder spraying technology for material modification, the two phase turbulent numerical computation of the jet field is very important.
在冷喷涂材料表面改性技术研究中，圆喷嘴气、固两相可压缩紊流射流的流场计算非常重要。
I often see a jet spraying pesticides on them and I'm worried about its hurt to our health.
常看到空中有喷农药的飞机在给这些病了的白杨树喷药，我真担心这些农药会不会对人体造成什么伤害。
