气流分离

The dried materials after the de-watering will go up with the heat-air flow. The step rings will stop and keep the big particles. Small particles will be discharged out of the drier from the ring center and will be restored by the whirl separator and dust remover. The not-fully-dried or big piece materials will be sent to the wall of the equipment by centrifugal force function and be smashed again after they fall down to the bottom.

脱水后的干物料随热气流上升，分级环将大颗粒截留，小颗粒从环中心排出干燥器外，由旋风分离器和除尘器回收，未干透或大块物料受离心力作用甩向器壁，重新落到底部被粉碎干燥。

The convective heat transfer of upper surface of PGA is enhanced due to flow separation and reattachment caused by mounting obstacle.

由于安装台阶引起气流在PGA封装上表面的分离和再附着，导致对流换热的强化。

In concurrent distillation, the upward flowing vapor atomizes liquid in a tray and carries it up to collectors in the tray above. There the liquid is separated and sent back down via a side downcomer.

并行蒸馏法过程中，在塔板内向上的气流将液体喷射成雾状并将其带到塔板上方的回收处，在那里液体被分离出来，经旁边的管子流到下面。

When the amount of trash in dustbins passes a defined threshold, a central control system will switch on turbines to cut air pressure in the tunnels and suck in the trash, which is then separated, compressed, filtered, purified, deodorized and ejected at a trash station.

当垃圾箱中的废弃物达到一定的临界值时，中央控制系统会启动涡轮抽气装置，产生负压气流，将垃圾箱中的垃圾吸入输送管道内。所有废弃物最终将被传送至垃圾站，经过分离、压缩、过滤、净化、除臭等过程后排到户外。

It is an important task for the research of air classification to achieve denslty-domlnant separation.

实现颗粒按密度为主导的分离是气流分选研究的关键。

Another key advance: a vertical gas flow cell structure is combined with wave flow-channel separators for an even more compact, lightweight design

另一个关键的推动：1垂直气流细胞结构结合起来，波流量为更轻巧的设计，通道分离

The results show a reversed-flow region is formed at the tip of the pressure side due to the influence of the outside hot combustion gas and the pressure side tip thickness. The pressure gradient makes the coolant flow exit from the trailing edge slot first separates from the trailing edge cut-back, and then affected by the expansion wave, the coolant gas reattaches the cut-back of the trailing edge after passing a certain distance.

研究表明，由于外流和叶片叶盆尾缘厚度的影响，叶盆尾缘端部形成局部回流，叶片尾缘劈缝气体流出后受压力梯度的影响先抬起与叶背面分离，在流过一段距离后由于跨音速流膨胀波的作用，冷气流再次附着在叶背尾缘上。

So people mor and more pay attention on curing the air pollution with superiority difference between the electrical duster and machinery duster (gravity serrling centrifuge . lavation、filter and so on) is that the former duster enforce the power of dust settling only to exert on dust itself .but the latter duster enforce the power of dust settling to exert on whole air current .

由于电除尘器迫使尘粒沉降的办只施加于颗粒本身，而不是施加于全问气流，这就是电除尘器有别于机械除尘（重力沉降、离心分离、洗涤、过滤等）最重要的代越性。

The performance of energy separation on the vortex tube designed by the author is studied at different cold mass flow ratios, and the characteristic curve has been drawn.

对于本文设计的涡流管，研究了不同冷气流率时涡流管的能量分离特性，并且绘制了性能曲线。

When a wing stalls the wing loses most of its downforce and drag.A single element wing will then stall, as the flow breaks up under the wing

但是当超过临界点，尾翼气流完全分离从而导致失速的时候，空阻会大幅减小，下压力也会戏剧性的降低。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
