velocity of exhaust信息详情
排汽速度,排气速度
velocity───n.【物】速度
exhaust───n.废气;排气管;v.使精疲力尽;耗尽;彻底探讨;排出(气体)
exhaust fan───n.排气风扇,抽风机;n.[建]排气扇;[建]抽风机;排风机
velocity profile───速度剖面(图),速度分布图,速度变化图
muzzle velocity───初速;出口速度;初速度(弹出膛时的速度)
exhaust stroke───[机]排气冲程;[机]排气行程;排气冲程,排气行程
constant velocity───常速度,等速度; 恒速;匀速;等速度;恒速度
angular velocity───[力]角速度
valved exhaust───带阀排气
The exhaust velocity, though, is enormous—more than ten times that of a chemical rocket—and this makes ion propulsion extremely efficient.───但其排气速度却异常惊人,大约为化学燃料火箭的十倍—这使得离子推进器的效率非常高。
The metal's high ignition temperature of more than 6,920 degrees Fahrenheit forces exhaust gases out at high velocity to propel rockets upward.───这种金属高达6,920华氏度的燃点,释放高温度的气体推进火箭前进。
Following the gradual enlargement of steam generation pressure, the flow velocity of exhausting steam is accelerated; then, the valve core is pushed upwards to block an air exhaust passage.───随着产生蒸汽的压力逐渐增大,排出蒸汽的流速加快,将阀芯上推堵住排气通道。
