喷嘴

5 Mol/L nitric acid solution in nozzle plate pulsed column have been studied.

研究了喷嘴板脉冲萃取柱中正辛醇- 0 5mol/L硝酸体系的液泛通量、分散相存留分数等流体力学特性。

The results show that increase of the pre-expansion pressure, decrease of the pre-expansion temperature and the nozzle diameter result in increase of supersaturation and nucleation of the supercritical solution and decrease of the particle size. The supersaturation in the course of RESS can reach 10〓 and nucleation rate is about 10〓 particles m〓s〓.

计算结果表明，预膨胀压力增加，超临界溶液在快速膨胀过程中过饱和度提高；预膨胀温度提高，超临界溶液在膨胀过程中的过饱和度和成核速率降低；喷嘴的直径减小，流体密度降在膨胀过程中增大，从而导致溶液的过饱和度和成核速率提高。

The preparation procedures were optimized by orthogonal test L9（34） with the mean particle size and the amounts of total-phenol as indexes. Factors of the extraction pressure and temperature,diameter of nozzle, pre-expansion temperature were evaluated for their effects on preparation process.

以平均粒径、厚朴酚、和厚朴酚的总酚含量为考察指标，采用L9（34）正交实验，对影响RESS制备厚朴纳米液的因素（萃取温度、萃取压力、喷嘴孔径、预膨胀温度）进行优选。

Test data collected by 90°are inlet nozzle test unit is instroduced ,according to international standard,Test data such as inlet and outlet pressure,fan pressure,efficiency and etc.are computed.

介绍了用90°弧形进口喷嘴试验装置采集试验数据，再根据国际标准对风机的进出口压力、通风机压力、效率等试验数据进行了计算。

Input is simply a list of propellant ingredients, as well as chamber pressure and nozzle exit pressure.

投入，简直是名单推进剂成分，以及商会的压力和喷嘴出口的压力。

As a result, the pressure peaks on the nozzle surface are reduced, and overall performance suffers.

因此，压力峰对喷嘴表面的减少，整体表现受到影响。

P e and P o are the nozzle exit pressure and the chamber pressure, respectively.

p e和P O的喷嘴出口的压力和会议厅的压力，分别。

A plot of the pressure distribution along the nozzle (figure 4) provides a good way of summarizing its behavior.

阴谋的压力分布沿喷嘴（图4 ）提供了一个良好的方法，总结其行为。

Eventually we will have lowered the back pressure enough so that it is now equal to the pressure at the nozzle exit.

最终我们将有降低回压足以使现在是相等的压力，在喷嘴出口。

By reducing this angle, additional flow turning is produced, and then, an increase in nozzle wall pressure is created.

通过减少这个角度来看，额外的流动转折，是制作，然后，增加了在喷嘴壁面压力是创建。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
