气流

Numerical simulations on the quasi-steady and unsteady flow in Aachen 1-1/2 Axial-Flow turbine stages are performed in this paper, and the influences of the rotor-stator interaction on the fluctuating velocity, flow angle, wall-pressure and loss mechanism are discussed.

本文对Aachen一级半轴流式透平进行了准定常及非定常流动的数值模拟，讨论了引发动静干涉效应的主要因素，分析了非定常效应对叶栅通道中脉动速度、气流角、型面压力分布以及损失结构的影响。

The new study points out that the 20-year-old model for spider "ballooning"—which assumed that spider silk is rigid and straight and spiders just hang at the bottom—was flawed when applied in moving, turbulent air.

新发现指出20年前提出的&气球模式&有漏洞，特别是把它运用到蜘蛛遇到流动的，不稳定的气流的情况下。&气球模式&假设蜘蛛丝是又硬又直的，而蜘蛛则吊在丝网的末端。

Danyang xinxing textile equipment accessory factory is specialized in producing all kinds of airflow spindle,rotating cup,separating bar,pressing wheel,movable passageway,resisting twister,shock absorber and so on.we are capable of cooperating in research and development of new products.at present we act as agent in importing altax,lida,rotating cup,separating bar,german needle cloth,jinjing needle cloth,glaf needle cloth and bearing.

丹阳市新兴纺机专件厂是专业生产各种型号的气流纺、转杯、分梳辊、压轮、活络通道、阻捻头、减震套及各种小配件并合作研制、开发的专业化工厂。工厂并代理进口艾立泰克斯、立达、转杯、分梳辊、德国针布、金井针布及格拉夫针布、轴承。

The increase in ash depth from the rear to the front changes the resistance of the fuel bed plus the ash to the air flow.

灰层由后而前增加，这样就改变了燃料床加上炉灰对气流的阻力。

The updraft gasifier achieves the highest efficiecy as the hot gas passes through fuel bed and leaves the gasifier at low temperature.

气化炉的上升气流，实现了作为最高 efficiecy热气体穿过燃料床和叶在低温气化炉。

To go big S bend pipe, air flow more smoothly.

管道走的大S弯，气流流过更加顺畅。3。

Take a small S bend pipe, flow smoothly to lead to this degree bend greatly affected.

管道走的小S弯，气流要过这个弯顺畅度大受影响。3。

Rather than relying on the vacuum chamber alone, the Twin Chamber Blow Off Valve harnesses boost pressure in a second chamber to assist in opening the relief valve.

因而无论在突然增速和减速的情况下，双腔排气阀都有着良好的阀门效果，同时又不损失气流效应。

The control of the whole test-bed is completed by a Programmable Logic Controller. The place of seeds are tracked by the sensor, it can obtain position of any seeds fleetly and exactly. The open or close of high-pressure airflow is controlled by the magnetic valve, which blow the seeds into the container according its grade information .The software for the communication from PC to PLC was compiled , which was based on Visual C++, it was proved to be effective and friendly to operation .

本研究选择可编程控制器PLC来实现对整个试验台的控制，由色标传感器对种子位置进行实时跟踪，快速、准确地获得运动中每一粒种子的位置信息，通过电磁阀控制高压气流的通断，将种子按其级别信息吹入相应的容器里，研究还包括PC机与可编程控制器PLC之间的通讯功能的实现。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
