查询词典 straw-splitter

The shredding of agro-residues, such as corn stalk, straw, wood sawdust and other herbaceous biomass, were investigated in this dissertation. According to the machinery mechanics of shredding, the components, shearing strength and pressive strength of the biomass were analysed in theory, which played a critical role during the shredding process. And the powder was examined by Scanning Electron Microscopy. It was founded that shearing,splitting and grinding force were appropriate for shredding biomass. The results also showed that primary shredding was the bulk shredding model, which was mainly affected by shearing and splitting force, therefore the curly knife and the straight knife were useful; while the fine shredding was the surface shredding model, affected by splitting and grinding force, and the straight knife useful.

本文以农林废弃生物质为研究对象，结合机械力破碎基础理论，从影响其破碎的化学组分和剪切强度、抗压强度等力学角度进行了理论研究，并运用扫描显微镜对破碎产物的微观结构进行了实际分析，结合二者得出如下结论：最适合生物质的施力方式为剪切力、劈碎力和磨削力；生物质粗破碎为体积破碎，主要受剪切力和劈碎力作用，刀片宜设计成弯口刀和单面直刃刀；细破碎为表面破碎，主要受剪切力和磨削力作用，刀片宜设计成双面直刃刀。

In trial 2, according to the similarity of calving date and milk yields, 25 primiparous Holstein cows were divided into five equal groups in a randomized block design with 49 days period. The general diet of dairy farm was fed to cows of control. The alfalfa block 2.7kgd^(-1 was substituted respectively by rice straw block Ⅰ,Ⅱ,Ⅲ or Ⅳ as treatments.

Everybody knows the story of another experimental philosopher who had a great theory about a horse being able to live without eating, and who demonstrated it so well, that he had got his own horse down to a straw a day, and would unquestionably have rendered him a very spirited and rampacious animal on nothing at all, if he had not died, four-and-twenty hours before he was to have had his first comfortable bait of air.

人人都知道另一位实验哲学家的佳话，他自有一套马儿不吃草也能跑得好的高见，还演证得活龙活现，把自己一匹马的饲料降到每天只喂一根干草。毫无疑问，要不是那匹马在即将获得第一份可口的空气饲料之前二十四小时一命呜乎，他早就调教出一匹什么东西都不吃的烈性子骏马来了。

The results show that biomass owns higher NO removal efficiency than pulverized coal. NO removal efficiency of three kinds of fuels increases by different extent through the increase of reburn fuel fraction and the decrease of the excess air ratio. NO removal efficiency of corn straw is the most efficient; rice husk is medium, pulverized bituminous coal is the lowest. Within the certain reburn resident time (650 ms), NO removal efficiency increases quickly with the resident time.

研究表明：生物质脱硝能力明显高于煤粉，提高再然比例及减小过量空气系数，3种燃料的脱硝率有不同程度的提高，其中秸秆脱硝率最高，稻壳中等，煤粉最低；在一定的再燃停留时间内(650 ms)，延长停留时间，脱硝率增加，超过这一停留时间，脱硝率增加缓慢。
