查询词典 jet

An analytical model was built up on the jet deflection in the crossflow by applying the theorem of momentum, which takes full account of mixing between the upstream fluid and burner jet, and of the total pressure difference between the two sides of the jets. Through analysis of this model, experimental study and numerical simulation, effects of the nozzle spacing ratio, width of the furnace corner, width of the nozzle and imaginary circle diameter on the aerodynamic field in the furnace were obtained.

本文综合考虑了炉内旋转气流与燃烧器射流的混合和燃烧器射流向火侧与背火侧的全压差等因素，应用动量定理建立了横向气流中射流偏转的分析模型，并结合冷态模化试验和数值模拟计算，得到了燃烧器间隙率、炉膛切角、喷口宽度和假想切圆直径等因素对炉内空气动力场影响的规律。

Ink-Jet Printer An ink-jet printer sprays small droplets of ink at high speed onto the surface of the paper.

激光打印机使用激光光束光源在磁鼓上产生小点一样的图像，用磁化的带电的像墨一样的碳粉处理这些字符，然后从磁鼓传送到纸上。

Not until October 1945 did the Americans expect to have a jet airplane (and in the event, two years after the end of the war, the ME 262 being flown at Wright-Patterson AFB, Dayton, Ohio, was still judged superior to the new USAF-80 jet fighter).

到1945年10月前，美国才有望拥有喷气飞机（例如，战争结束两年后，飞行在俄亥俄州戴顿县莱特—帕特森空军基地上空之ME262，比较起新式美国空军*—80式喷气战斗机来，还被判定更为出色）。
