轴管

Here, you can see the Mabuchi 550 12-volt motors, the Graupner Speed-Profi 50 Reverse BEC Speed Controllers, the Master Airscrew 3.0:1 Ratio Gearboxes, the brass stuffing tubes with Oilite bearings and O-ring seals and the 3/16 diameter propeller shafts.

在这里，您可以看到万宝至五五零一二伏马达，格劳普纳速度Profi的50扭转选委会的速度控制器，主airscrew 3.0：1的比例，变速箱，黄铜填料管oilite轴承和O形密封圈和3 / 16 直径螺旋桨轴。

It absorbs the axial.radial and angular displacement and also a vibration and noise isolating device.

它通过波纹管的柔性变形来吸收管线的轴向、径向和角向位移，同时也能起到隔振降噪效果。

The effect of heat source location on the heat transfer of an axially grooved heat pipe was investigated.

探讨了轴向槽道热管垂直安装时热源位置的不同对热管工作特性的影响。

Unsteady flow of power-law fluid in eccentric annuli with the inner cyinder reciprocating axially is studied in this paper.

本文研究了幂律流体在内管做轴向往复运动的偏心环空中非定常流的流动规律。

To evaluate the effects of axially loaded MR imaging on the lumbar spinal canal, and its clinical value.

评估仰卧位轴向负荷腰椎MRI检查对椎管的影响及其临床意义。

In operation, the downhole devices will be laid down with tubings which will move up and down using the operation machine. Since the injection head can rotate in the determined speed, the rotating flow, compared with the conventional stable axial flow, can prevent the sands from depositing in the horizontal annular and washing the screen. The jet from high-efficiency jet nozzle will wash the screen directly with concentrated hydro-power. The working fluid can be clean water, without damage to the formation.

作业时用油管下入该井下装置，利用作业机带动油管上下移动，由于喷头可按照既定速度旋转，返回流体在水平段由常规的平稳轴向流动变为旋转流动，既可实现对防砂管的全方位解堵，又能避免砂粒沉积；高效喷嘴产生的射流直接对着防砂管冲击，能量集中；工作介质为清水，不会对地层带来二次污染。

The automatic servo mechanism has coaxial walking wheel and driving wheel, chain driving among the driving wheel, unwinding wheel and pipe reel, and slip clutch mounted between the pipe reel and the winding wheel.

本装置的行走轮与驱动轮同轴，驱动轮与放线轮和管线卷盘之间由链条传动，滑差离合器装在管线卷盘与收线轮之间。

They are used where some pressure head is prevalent, such as in a duct system.

管状轴流风机是固定在一定长度的管状支架上的螺旋桨式风机，它们通常保持一定压力值，例如在排尘系统中。

Based on the integration of the results of acoustic andfluid dynamic analysis, this paper points out that synthetical acoustic and fluiddynamic performance of muffler can be obtained by using square expansion chamber,by stringing together several podgy expansion chambers, by applying noise absorbingmaterial on chamber walls, by making chambers and pipers co-axial, by adding filletson the end of intruding pipes, and by making the diameter of outlet pipe a little greaterthan the diameter of the inlet pipe.

通过综合流体力学和声学有限元两方面的分析的结果，指出了采用方形扩张腔，采用多个短粗扩张腔串联，扩张腔壁面附吸声材料，使各管道同轴，在插入管端口加上圆角，并且令出口插入管管径略微大于入口插入管管径可以使消声结构获得最佳的声学和流体力学综合性能。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
