空气冷却

The heat-pipe air condenser can be used to control the temperature of the continuous quenching medium accurately,which could guarantee the microstructures and mechanical properties of the work pieces during heat treatment,and it is very effective in practical application.

针对连续淬火介质在工作中存在的冷却问题，提出由空气冷却代替水冷系统，研制出的热管空冷器可以精确控制连续淬火介质温度，保证热处理工件的金相组织和力学性能，在实际应用中取得较大成效。

There are generally two kinds of cooling systems: water cooling system and air cooling system.

一般有两种冷却系统：水冷系统和空气冷却系统。

The quality changes of pakchoi in cold storage with vacuum cooling and air cooling, at 2℃ for 7 days, 10 days, 14 days, 19 days and 29 days were studied.

摘 要 试验研究了小白菜采后真空冷却和空气冷却后，在2℃条件下冷藏7天、10天、14天、19天和29天的品质变化。

Uses two types of automobile engine cooling method, that is, air cooling and water cooling.

汽车发动机采用两种冷却方式，即空气冷却和水冷却。

The air-cooled or liquid-cooled component can be hot or cold, as needed.

空气冷却或液体冷却组件可以是热或冷，根据需要。

Potable water is obtained from sea water (or other non-potable water) in reservoir 20 by passing a stream of atmospheric air over briaded-cotton wick plates 22, which are saturated with the sea water, so that the air takes up water-vapour, drawing the moistened air by if an 25 in section 17 where the air is cooled by coils 32, 33 and water-vapour condenses.

的食水是从海水在水库20通过流大气超过briaded棉芯板22 ，这是饱和的海水，所以认为空气占用了水汽，绘制湿空气中，如果一25日在第17条的地方，空气冷却线圈32 ， 33和水汽凝结。

They are generally two different types of cooling system:water-cooling system and air-cooling system.

他们通常是二个不同的类型冷却系统：水-冷却系统和空气-冷却系统。

Additionally, the air cooling zone should be set up so as to cool the steam and air mixture. Thus, the steam and air mixture supercooling can be enlarged, the working medium loss reduced and the burden of air ejector taken away.

另外，应该设置空气冷却区，使蒸汽-空气混合物得到冷却，以增大排出的蒸汽-空气混合物的过冷度，减少工质损失，并降低抽气器的负荷。

Besides, it can avoid the direct flow of steam and air mixture to air extraction outlet, in case of the load accretion for air ejector.

设置当汽板，防止主凝结区的蒸汽与空气冷却区的空气混合，影响传热效果；并防止蒸汽不经过主凝结区直接进入空气冷却区而增大该区域的热负荷；还可防止蒸汽-空气混合物不经过空气冷却区，直接流入抽气口，而使抽气器负荷增大

The preparative technique of solid lubricant is cold-press sintering method.The micro-structure , friction surface, lubricant transfer film surface of base material was characterized by SEM; XRD was used to do phase analysis. The degrees of crystallinity of pure PTFE under the different conditions of water cooling, air cooling and furnace-varying cooling were made comparison by XRD. The thermal stability of pure PTFE and solid lubricant was analyzed by DSC-TG; The composition and valence state of elements in the surface of carbon fiber ,solid lubricant before and after friction test and lubricant transfer film were characterized by XPS; The frictional property of solid lubricant was tested by pin and disk test rig .

用SEM表征原料微观结构、摩擦表面及润滑转移膜表面形貌：用XRD进行原料物相分析，及比较水冷却、空气冷却、随炉冷却三种工艺条件下的纯聚四氟乙烯树脂的结晶度；用DSC-TG分析纯聚四氟乙烯树脂及固体润滑剂的热稳定性；用XPS表征碳纤维表面、固体润滑剂摩擦前后表面、润滑转移膜表面的元素组成、价态变化；用销盘式摩擦磨损试验机对固体润滑剂进行摩擦性能测试；采用专用的台架模拟试验机对固体润滑剂镶嵌轴承套与钢轴摩擦副间的摩擦磨损性能进行测定；用莱次偏光显微镜测试固体润滑剂的硬度；用材料试验机测试固体润滑剂的抗压强度等。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
