下雾

The swipe test is where you take your clean finger, and swipe it briskly across the finish with the wax on it. If the paint is clear, without residue where your finger made the swipe, the wax is ready to wipe-off. If the area you have swiped is smudgy, or streaky, or there is noticeable wax in the swipe area, then the wax has not set-up long enough and you should allow more time for the wax to set-up before your remove it.

擦拭测试就是使用你乾净的手指去划过上完蜡的烤漆表面，如果你用手指擦拭过的漆面是光亮的且没有任何残留物质，这意味著你可以准备下蜡了，如果你擦拭过的区域是雾状不清透的、有条纹的或有明显的蜡残留在擦拭的区域，则这表示蜡的成形等待时间还不够，在你移除蜡之前你还需要等待更多的时间。

Such as: calibrating the laser system, calibrating the measurement region and focusing the CCD camera for the diffuser passage with complex shape, selecting the best incidence angle for the laser sheet,, setting the time parameter including the time between pulses and the time between records, designing the laser system, and selecting water fog with 1～5μm diameter as seedings for PIV measurement after comparing several particles. All of the work is useful to accumulate the PIV measurement experience in turbomachinery. 2. Experimental research of the unsteady flow in diffusers The instantaneous velocity fields within the vaneless and vaned diffuser were measured by using PIV technique.

本文在国内首次进行PIV测量系统对离心风机扩压器内部非定常流动的测量，为此，作者作了必要的实验前期工作：双谐振激光器工作特性的标定；针对扩压器复杂的流道形状，解决了片光源照射区域位置的标定和CCD相机的聚焦等问题；为复杂流道形状的扩压器内部流动的PIV测量选择了最佳片光源入射角度；选择了合适的PIV测量时间参数；为实现非定常内流的PIV测量设计了PIV系统的光路布置；根据非接触测量示踪粒子的选取原则，对几种示踪粒子进行了筛选，最终1～5μm的水雾粒子在本文实验条件下获得最佳效果。

In particular the atmospheric pressure chemical ionisation and the electrospray ionisation methods are nowwidely used in routine analysis (see also section on PTR-MS and HOx radicals below).

尤其大气压化学电离和电喷雾电离方法现在广泛应用于常规分析（请参见PTR 和 HOx 下有关基础）。

Effects of air swirl intensity on atomization and combustion performance of effervescent atomized spray were investigated under different conditions.

对不同空气旋流强度下气泡雾化喷嘴出口下游喷雾流场特性及燃烧特行进行了诊断与分析。

The working process of set is as follows; the liquid of raw material is pumped in through diaphragm pump. The liquid of raw material atomizes into tiny droplets. Then it gathers with hot air and fall off. Most parts of powder material will be collected through the outlet of discharge at the bottom. The wasted air and fine power will be separated through cyclone.

本机组工作过程为料液通过隔膜高压输入，喷出雾状液滴，然后同热空气并流下降，大部分粉粒由塔底排料口收集，废气及其微小粉末经旋风分离器分离，废气由抽风机排出，粉末由设在旋风分离器下端的收粉筒收集，风机出口处还可以装备二级除尘装置，回收率在96-98%以上。
