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 clamping diodes conduct only once in a switching period, and the resonant inductance current is smaller in zero state, leading to a higher efficiency and reduced duty cycle loss. the operation principle of the improved converter and the comparison with the original converter are analyzed in this paper. the effect of the blocking capacitor in series with the transformer or resonant inductance is discussed, and a best scheme is determined
本文將諧振電感和變壓器交換位置,使變壓器與滯后橋臂相連,這樣箝位二極體在一個開關周期中只導通一次,同時零狀態時諧振電感電流較小,有利於提高變換效率和減小占空比丟失,本文分析改進后變換器的工作原理,並與改進前的變換器進行對比,討論隔直電容在不同位置對變換器工作的影響,確定一種最佳工程方案。A circuit or device that converts a dc input voitage to a regulated output woltage, the output voltage may be lower, higher or the same as the input voltage, switching - regulator dc - dc circuit most often require an inductor or transformer to achieve t - he regualted output voltage, wwitching fegulator circuits can achieve a higher level of power efficiency whec compared to non - wwitching techniques
指一電路或儀器可將一直流輸入電壓換成一高速過的輸出電壓,此輸出電壓可為較低,較高或輸入電壓相同,互動式直流對直流調整電路通常需要一電感或變壓器以達到所要的輸出電壓,交換式調整電路和非交換式技術比有較高的功率效率。Because the feeder short circuit current of subway is very great, the plug - in boards of input and output are different from the ac feeder protection. after analyzing and comparing the two popular input components, the thesis choices the shunt. in addition, the thesis gives the original design of output plug - in board
