相比之下，火箭的化学能功率是推进力的一半乘以排气速度。
By comparison, the chemical power generated by a rocket equals one half the thrust times the exhaust velocity.
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 exhaust velocity, though, is enormous—more than ten times that of a chemical rocket—and this makes ion propulsion extremely efficient.

Theoretically, it is proved that for both these engines, the properties of two-phase flow in nozzle can be analysed with a common combined parameter which is equivalent to exhaust velocity.
从技术上讲，化学燃料火箭的最大速度增长比较低。这就是说，它们的排气速度还不足以将火箭的速度增加到非常快的程度。
In technical terms, chemical rockets have low maximum velocity growth, which means that their exhaust velocities are not high enough to impart very high speeds to the rocket.
这并不意味着活塞将以两倍于正常速度上下运动，因为浪费的火花出现在排气行程中，和没有任何压缩。
This does not mean that the plugs will wear at twice the normal rate, as the wasted spark is on the exhaust stroke, and is therefore under no compression.
例如，同样的数量，位置和进气口和排气口类似的风格，但在这里提炼，综合和利用，以改善道路气流速度和整体效果。
For example, the same number, position and similar styling of intake and exhaust ports, but here refined, combined and utilized to improve airflow and overall effect at road speeds.
但是，较快的注射速度常常要与“排气不良”问题之间达成妥协，“排气不良”是指夹带空气的熔体前锋的烧焦现象。
However faster filling speeds are often compromised by problems such as' gassing '- the burning of the melt front due to entrapment of cavity air.
这些参数包括冷却速度、耗电量、冷藏室温度、冷冻室温度、冷凝器温度、压缩机吸气温度和排气温度等。
Those parameters included pull down speed and power consumption of the refrigerator, temperature of cold storage chamber, freezing chamber, condenser, suction and discharge pipes of compressor, etc.
试验结果表明排气塔后部的尾流区能引起速度亏损、湍流增强和下冼现象。
Experiment results show that wake region behind wind tower can cause velocity deficit, turbulence excess and downwash phenomenon.
同时计算得到了静止式气波制冷机内部流场的速度、压力分布，捕捉到了射流“卷吸”和充排气的掺混现象。
The simulation obtains while process of fluidic attachment and switch and distribution of velocity and pressure of flow field.
如果你不知道你的速度上不去是因为引擎、排气装置、空体动力学、轮胎气压，或是赛车手，那么你将无法获胜。
You won't know if your poor speeds are caused by the engine, the exhaust, the aerodynamics, the tire pressure, or the driver.
另外，还分析了排气孔口瞬时速度的影响因素，对瞬时速度进行了计算。
In addition, the instantaneous velocity is calculated, and its influencing factors are analyzed.
内部排气阀增加下冲速度。
排气管内轴向速度分布与分离空间内的分布形态迥异。
The distribution of time-averaged axial velocity in the outlet tube was very different from that in the separation space.
利用它对国产OFPI—220型SF_6断路器进行的计算结果表明，改变动触头排气孔位置及电弧对动触头内腔中气体的热效应可明显提高开断电流时灭弧室压力上升速度。
The results show that the position of the exhausting gas hole and the arc heat effects on the gas inside the hollow moving contact have obviously raised the pressure rising speed.
正面排气设计加快声音的传播速度，即使在大音量情况下失真度相对较低。
The AS8's bottom-firing and front-ported design means you'll hear quick, precise bass with low distortion, even at higher volume levels.
