決不允許為了吹除雜質從高壓氣源，例如氣瓶中放出氫氣。做類似事情時，只能用氮氣或空氣作為外在氣源。Moreover, it has been pointed out that the hydrogen engine used in ? cylinder injection with high pressure can increase volumetric efficiency and compression ratio, - therefore, the performance indexes in this engine, such as output power, thermal efficiency, range of thickness of mixture with normal operation and nox emission, can be improved, and it is possible for the engine to realize rapid combustion of thin mixture, so abnormal combustion, such as backfire, pre ? ignition, can be controlled effectively
指出了採用內部混合氣形成方式且高壓噴射的氫發動機，有利於提高充氣效率和壓縮比，從而改善發動機的動力性和經濟性；有利於擴展發動機正常工作的濃度范圍；並且有利於實現稀薄混合氣快速燃燒，從而可以有效地抑制早燃、回火及爆燃等異常燃燒和no _ x排放量。試驗指出了發動機的點火正時、噴射正時及噴氫量對發動機的性能、異常燃燒、 no _ x排放量有很大影響。The scientists want to find out whether the energy output from the burning hydrogen ? which reached a heat of more than 3, 000 degrees fahrenheit ? would be enough to power a car or other heavy machinery
科學家們正試圖弄清氫氣燃燒時，釋放出溫度高達3000華氏度的能量，能否驅動一輛轎車或其它重型機械設備。She hopes that hrl staffers can eventually identify a “ goldilocks ” compound with sufficient adsorption capacity that will release hydrogen at 150 degrees c or even lower
她希望hrl的工作人員最後可以找出一個最適合的化合物，具有足夠的吸收能力，把釋放出氫氣的溫度降到150 ，甚至更低。Abstract : it has been discovered that the coke formed in ch4 coupling under plasma can be eliminated via pure h2 discharge in the system. eliminating coke under plasma with positive or negative high voltage in dc electric field has been compared with that in ac field. the elimination of coke takes place only on the negative of the two electrodes in dc field, while on both electrodes in ac field. the coke on the reactor walls can be eliminated with either positive or negative high voltage and in either dc or ac field. based on the experimental facts, hypotheses of the reaction mechanism are suggested. quantity of eliminating coke depends on diametrical ratio between reactor and the electrode, input power and electrode materials
文摘:發現了等離子條件下甲烷偶聯反應中形成的積炭可以通過該體系中純氫氣放電而消除.將消除積炭使用直流電場的正高壓和負高壓與使用交流電場作了比較，發現直流電場中無論使用正高壓還是負高壓，只有陰極上的積炭可以被消除，而交流電場中兩極積炭均可被消除，反應器壁上的積炭在以上任何情況下均可被消除.基於實驗事實提出了機理假設.消除積炭的量與輸入功率、反應器對電極的直徑比以及電極材料有關The redox of v ( ) / v ( ), v ( ) / v ( ) couple on the graphite displayed one electron quasi - reversibility. it is proved that trace in3 +, sb3 + can inhibit cathodic hydrogen evolution during the charge process by increasing the hydro - gen overvoltage in addition that sb3 + is a stabilizing / kinetic enhancing ion. during the charge / discharge process, cross - mix and self - discharge rarely happened. the maximal energy density of the lab - level vanadium battery is 21 wh / kg. the capacity efficiency of the lab - level vanadium battery is as high as 94. 7 %
釩電池充電末期，會發生水的電解反應，痕量銦離子的加入提高了析氫過電位，抑制了充電過程中負極氫氣的析出；銻離子的加入不僅可以抑制氫氣的析出，還提高了正極反應速率，增強了正極表面的穩定性。實驗中得到的最高質量比能量為21wh / kg ，充放電過程中僅有極少的交叉混合和自放電發生，自製釩電池的容量效率可高達94 . 7 %When heated, these metal hydride powders decompose, liberating the gas
