喷嘴

In magnetorheological jet polishing,the stable and collimated jet of magnetorheological fluid magnetized by a local axial magnetic field near the exit of the nozzle was used to polish the remote surface in a deterministic precision process.

磁射流抛光利用喷嘴出口附近的外加局部轴向磁场稳定磁流变液射流，产生稳定、汇聚的射流束进行远距离确定性精密抛光。

We would have to disassemble the nozzles and hoses, and it would take three to four hours to clean the machine.

我们将要拆卸的喷嘴和软管，并且将需要3至4个小时的清洁机器。

In the study of flow oscillation and discrete frequency noise of impinging jet, it is found that there is a critical pressure ratio for a given nozzle and a nozzle-to-plate distance.

发现对于给定的喷嘴和冲击距离，存在一个压比临界点，当压比高于此临界点值时，流场振荡和离散频率噪声被显著抑制乃至消失。

He pointed the nozzle of the fire distinguisher at the flames.

他将灭火器的喷嘴对着火焰。

Here we use a converging diverging nozzle to connect two air cylinders.

在这里，我们使用了不同的收敛喷嘴连接两个空气气瓶。

The usual configuration for a converging diverging nozzle is shown in the figure.

通常的配置趋于发散喷嘴是表现在数字。

The characteristics of the system were estimated by using correlative theory considering the effect of the drag force.

购买并加工制作了实验所需设备或器件(喷嘴、热源、压力泵和各种测量仪器等)，搭建了实验平台。

The system has a scan volume of 8 x 2 x 2 metres and is able to inspect parts which have a complex, dual curvature geometry, by virtue of the fact that the motion of the squirters on each side of the part are totally independent - ie they are not linked by a bridge or any other constraining structure.

系统的扫描范围是8*2*2m，可检测复杂双曲面零件，该功能的实现主要是由于零件两边的喷嘴能够完全独立地运动-例如，他们不与桥连接或任何其他的阻碍结构连接。

Some conclusions are followed:(1)the reaction ratio of boron is 12% in primary combustion;(2)the degree of agglomeration can be decreased adopting boron coated with AP;(3)the content of oxygen is very important for afterburning efficiency;(4)the afterburning efficiency will be changed with different air-gas ratio;(5)the head distance of after-burning chamber is increasing, the circumfluence in the head of after-burning chamber is stronger and the distribution of fuel backward the after-burning chamber is more well-proportioned.(6)the combustion efficiency of DR will be improved by increasing the area of fuel nozzle.(7)the angle between dual air-inlets have complex influence with the combustion of DR.

通过本项研究，取得如下结论：（1）一次燃烧硼反应比例在12～15％之间；（2）AP包覆硼，可以降低硼结团度，有利于一次燃烧喷射效率的提高，也有利于硼在补燃室进行二次燃烧；（3）进气空气中的氧含量对二次燃烧非常重要；（4）对于一定配方的含硼富燃推进剂，不同的空燃比，二次燃烧效率不同；（5）补燃室头部距离的增加能增强补燃室头部回流以及提高燃料在补燃室后段分布的均匀性；（6）在一定范围内，增加一次燃气喷嘴面积能提高冲压发动机燃料的燃烧效率；（7）进气道夹角对补燃室内燃料的燃烧影响复杂。

Economization of air consumption: The support of ultra short pneumatic circuit and assistant nozzle saves about 10% consumption of air.

耗气量的节省：超短气路的设计和副喷嘴的支援控制，降低了约10%的耗气量。

I will endeavour to find you some assistance.

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。
