排气

It's a small thermal exhaust port,right below the main port.

是个反应炉排气口，就在主排气口的下方

Pump exhaust may contain solids, not to exhaust the work area or in front of people to avoid personal injury.

泵的排气中可能含有固体物，不要将排气口对着工作区或者人，以免造成人身伤害。

Figure 1 is the pump suction and exhaust rotor is located just off the termination of position, suction ports and exhaust ports have been sealed rotor sidewall.

图 1 是泵转子刚好位于吸气和排气终止位置，吸气口和排气口被转子的侧壁封住。

At present, the seal-type multi-stage vacuum pump is the most widely used access technology, a pump, it can be used as a separate low-vacuum equipment to the exhaust pump, it can be used as high-vacuum exhaust pump, when the first class, formed into a high demand for multi-stage pump.

目前，油封式多级泵是国内真空获得技术中应用最广的一种泵，它可单独用作低真空设备的排气用泵，也可用作高真空排气时的前级真空泵，组成成高要求的多级泵。

Figure 1 is the pump in the suction and exhaust of the process, pump suction chamber with the rotor rotation, the volume gradually increases, inhalation of gas; while the exhaust chamber volume is gradually reduced, the gas is compressed, thereby exhaust gas.

图 1 是泵在吸气和排气的过程，泵吸气腔随着转子的旋转，容积逐渐增大，吸入气体；而排气腔容积则逐渐减小，对气体进行压缩，从而排出气体。

At the same time, the resonant frequencies of four kinds of resonator are calculated by the programs which are made with Matlab software. The effect of resonator geometrical parameters on resonant frequency is theoretically analyzed. In order to carry out the acoustic and aerodynamics performances tests, seven resonators are designed and made, and a specialized engine intake silencer and exhaust silencers test bench was designed. The tests and analysis are performed as well.

在此基础上设计并加工了两类七个共振型进气消声器，研制了发动机进排气消声器性能测试实验台，开发了发动机进排气消声器声学性能测试软件，并在该实验台上测试了所设计的进气消声器静态工况下的传声损失，从实验的角度研究了共振腔的尺寸、形状对其共振频率的影响及其趋势。

The other is a larger exhaust resistance, such as a valve in the exhaust pipe on the road, small pipe, large damping sensors, non-specific silencer in the exhaust below the liquid level, the gas discharged into the closed or semi-closed containers.

另一类是排气阻力较大，比如在排气管路上有阀、细小弯管、大阻尼传感器、非专用的消音器、在液面以下排气、气体排往密闭或半密闭容器等。

The simplification of the flange joint is verified by the test and a simple and reasonable approach to one dimension modeling for the muffler with complex topology structure is provided.

本文建立了基于梁单元的排气系统一维数值模型，给出了排气组件的建模方法，特别对法兰接头的简化进行了实验验证，对具有复杂拓扑结构的消声器的一维简化提供了简单实用的建模方法。

This article has introduced noise reduction principles and methods, formation mechanism of vehicle exhaust noise, sorts of vehicle exhaust mufflers.

本文系统介绍了噪声控制的方法，汽车排气噪声的产生机理以及车用排气消声器的种类。

Based on sound intensity measurement and the simulation test of pass-by noise, the main noise source of a motorcycle is identified. The results show that the induction and exhaust noises of the engine are the main noise sources of the motorcycle, and their share of contributions to the pass-by noise are determined.

通过声强测试技术和加速噪声的模拟试验对摩托车的主要噪声源进行了识别研究，结果表明进、排气噪声是摩托车的主要噪声源，并初步确定了进、排气噪声对整车加速噪声的贡献量。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
