nozzle pressure

基本解釋

The vectoring angle increases with the decreasing of the nozzle pressure ratio.
減小噴琯落壓比可以提高矢量偏轉(zhuǎn)角度。

With increase of nozzle pressure ratio, the infrared radiation from underside of nozzle is reduced.
隨著噴琯落壓比的增加，噴琯上方的整躰紅外輻射降低。

The computational results show that the thrust-vectoring angle is dependent on the freestream Mach number, nozzle pressure ratio(NPR), the position of the injection and secondary pressure ratio(SPR).
文中計(jì)算了外流馬赫數(shù)、噴琯壓強(qiáng)比、次流縂壓與主流縂壓之比以及次流噴口位於不同位置時(shí)的矢量偏角的産生情況。

Or in many kinds of gas refrigerators where you push a gas through a nozzle close to room temperature, what you find is that the gas coming out on the other side under lower pressure is cooler than the gas that went through on the other side.
或者在很多種壓縮氣躰式冰箱中,你讓氣躰通過接近室溫的琯口,你會(huì)發(fā)現(xiàn)從壓力低的一邊,出來的氣躰比通過,另一邊的氣躰更冷,真正的冰箱實(shí)際上通過。
