  1. The gas field in pemfc means the gas distribution in gas source, gas inlet tube ( scale of m ), gas - blower, gas manifold ( scale of cm ), channel ( scale of mm ), diffusion layer ( scale of um ), hydrophobic layer and catalyst layer ( scale of nm ). the aim of changing the scales is to make oxygen reach reaction area as evenly as possible

    Pemfc的氣場指在氣源、進氣管(分米級) 、風機、進氣箱(厘米級) 、流道(毫米級) 、擴散層(微米級) 、疏水層(亞微米級) 、催化層(納米級)中的氣體分佈,每一級尺度的變化是為了氣體的進一步均勻化。
  2. The porous diffusion type silencer is widely used to reduce the air flow noise because of its small volume and high noise attenuating ability. the out case of the silencer plays a very important role in reducing noise. the effect of the hole ' s shape, diameter and the distance between neighboring holes as well as the matchup between the case and the sound absorbing material tube are investigated experimentally. the relation between the out - flow noise and the gas velocity distribution is carefully studied for two different kinds of matchup between the case and the sound absorbing material tube. some useful results are gotten, which may be valuable to the design of the silencer

    多孔擴散型消聲器由於其體積小、消聲性能高而廣泛應用到排氣噪聲的降低上,其外殼對消聲器的消聲性能具有重要作用.本文對此類消聲器外殼的孔型、孔徑和孔距以及外殼同消聲材料的配合方面進行了細致的實驗研究,特別對外殼與消聲材料的配合與其排放噪聲以及外部流場之間的關系進行了探討,得到了一些有用的結論,對消聲器性能的提高具有一定指導意義。
  3. Analysis of gas temperature radial distribution in neh2cubr laser discharge tube with diaphragms

    隔環結構的neh2cubr激光放電管氣體溫度徑向分佈
  4. Standard specification for seamless copper tube for natural gas and liquified petroleum gas fuel distribution systems

    用於天然氣和液化石油氣燃料分配系統的無縫銅管標準規范
  5. The influences of the inlet tube angle, backpressure and driving jet velocity on static pressure distribution in the gas - solid injector are calculated, and the effects of the inlet tube angle on particle bulk phase concentration and axial mean speed of particles in the gas - solid injector are analyzed firstly. the predicament caused by lack of measuring means on the particle velocity in experiments is solved

    分析了收縮角、背壓和氣體噴嘴出口速度對氣固噴射器內靜壓分佈的影響,以及收縮角對氣固噴射器內固體顆粒體積濃度場和顆粒平均速度的影響,解決了噴射器內固體顆粒速度試驗測試手段缺乏的困境。
  6. Standard specification for aluminum and aluminum - alloy seamless pipe and seamless extruded tube for gas and oil transmission and distribution piping systems

    氣體和油傳輸和配送管道系統用鋁及鋁合金無縫管和無縫擠制管標準規范
  7. Fluidized behaviors of ultra - fine powder caco3 of mean diameter 5 um in a spouted bed with a draft tube were investigated, studying the effects of geometry and operating parameters on the two - phase fluidized characters such as the initial spouted behavior, the solid circulation rate, the gas flow distribution in the spout and the annulus, and the solid flow in the annulus

    本研究以平均粒徑為5 m的caco _ 3超細粉為物料,對超細粉在導向管噴動床中的流化行為進行了系統的實驗研究,考察了床層結構和操作條件對起始噴動行為、固體循環速率、氣體在床層雙區中的分配以及固體顆粒在環隙區中的流動等氣固兩相流動特徵的影響。
