  2. Oxygen diffusion transport and electrochemical reaction in the oxygen cathode of direct methanol fuel cell ( dmfc ) have been expressed with the tffa model. model calculation has been carried out to investigate the effects of structural parameters of the dmfc cathode on the electrode performance, which is respectively represented by the curve of cathode overpotential versus current density. much attention has been paid to parameters including the porosity of the reaction layer, the thickness of the thin - film on the flooded - agglomerate, the radius of the flooded - agglomerate, the volume fraction of the flooded - agglomerates in the reaction layer

    本文首先運用tffa模型描述直接甲醇燃料電池（ dmfc ）陰極氧氣的傳遞和電化學反應過程，研究了過電位-電流密度曲線受陰極結構參數變化的影響程度，其中著重考慮了以下幾個參數：催化層的孔隙率，浸漬聚集體薄膜的厚度，浸漬聚集體的半徑，浸漬聚集體在催化層中的體積分數。
  3. Then, analytical work was carried out as follows : the ultimate analysis and physi - chemical analysis of the pyrolytic oil comprised a sketch of the fuel properties of the oil ; then, through the distillation analysis of the oil, the fraction composition of the " unrefined " oil was known. after that, a general knowledge of the aromaticity and saturation of the hydrocarbons in the oil was provided by the outcome of the ft - ir functional group analysis. also, from the analysis, the form of the polar functional groups and their distribution in different fractions of the oil were learned

    文中首先對不同熱解溫度下熱解油產率進行分析討論，然後，針對熱解油品質進行了一系列分析：通過元素組成和理化特性的分析，對熱解油作為燃料特性有了一個大致了解；通過實沸點蒸餾分析，得到熱解油作為一種未提煉油的餾分分佈，並為后續熱解油餾分的細入分析提供了前提；通過對熱解全油和各窄餾分的ft - ir官能團分析，對熱解油的芳香性、不飽和性有了整體的了解，並且清楚了熱解油中的極性官能團存在型式及其在熱解油不同餾分中的分佈。
  4. Aviation fuel fraction

    航空燃料餾分
  5. At the conditions with the same fuel injection quantity per cycle and the same engine speed, with the increase of the additive mass fraction in the fuel, the ignition and heat release timings brought forward, the peak of heat release rate increased and the operating range at low engine load was enlarged obviously. however, excessive additives will make the engine be prone to knock, run rudely and shorten the operating range at high engine load

    在相同循環噴油量和相同轉速的條件下，隨著添加劑質量分數的增加， hcci著火和燃燒放熱提前，燃燒放熱峰值提高，低負荷工況范圍明顯拓寬，但過高的添加劑質量分數會使得發動機爆震，工作粗暴，導致高負荷工況變窄。
  6. The composting of garden refuse on either a domestic or municipal scale may, therefore, be rendered unnecessary, because the organic composition of this material provides a derivative which is rich in cellulose content, producing a fuel fraction of high calorific concentration, and consequently of high commercial value

    家庭或城市的花園垃圾堆制肥料可能會進行不必要的提煉，因為此物質的有機組成提供一種衍生物，而這種衍生物含有大量的纖維素，纖維素可以產生高熱濃縮的燃料餾分，因此具有較高的商業價值。
