The penetration of a particle into the lung is influenced by air velocities breathing patterns . 颗粒物对肺的穿透作用受气流速度和呼吸形式的影响。
As the relative velocity between the two layers is increased, waves are formed at the interface . 当两层流体之间的相对流速增加时,分界面成为波浪型。
At a low flow rate, fluid merely percolates through the void spaces between stationary particles . 当流速低的时候,流体只是穿过静止的颗粒之间的空隙。
At some higher velocity individual grains will roll and slide intermittently along the bed . 在稍高一些的流速时,个别的颗粒沿着河床间歇地滚动和滑动。
The faster fuel movement through the high-speed system causes more air to bleed into the system . 经过高速系统的较高流速的燃油会引起较多的空气渗入系统。
To prevent clogging of the pressure tap by fine solids gas is bled into the bed at low velocity at the taps . 为了防止测压管嘴被微细颗粒堵塞,在管嘴处以低流速向床内注入气体。
Such damage is usually found to have been caused by hydrometer misuse, especially with synthetic separators . 通常所发现的这种损坏是由于应用流速计不当造成的,尤其是使用合成材料隔板。
With an increase in flow rate, particles move apart and a few are seen to vibrate and move about in restricted regions . 随着流速的增加,颗粒互相离开,并可看到有少量的颗粒在一定的区间内进行振动和游动。
The nature of sand movement depends on the particle size, shape, and specific gravity in respect to the associated velocity and turbulence . 泥沙运动的性质取决于颗粒的大小、形状和比重并与流速和紊动有关。
In hydraulic systems, the flow rate of the fluid may be considered as a through variable, and the pressure causing the flow may be the across variable . 在水利学系统中,流体的流速可考虑作流通变量,而引起流动的压力可考虑作跨接变量。
