coke n. 科克〔姓氏〕。 n. 焦(炭)。 mineral coke天然焦。 a coke oven 煉焦爐。 vt. 把…煉制成焦炭。 vi. 煉焦;成焦炭。 n. 1.〔俚語〕=cocaine. 2.〔美口〕可口可樂(=coca-cola)。 go and eat coke 別作打擾別人的事[少管閑事]。
Under extreme conditions of rapid coke forming materials, pore mouth blockage can occur . 在快速形成焦炭材料的極端情況下,孔口會發(fā)生堵塞。
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(fā)現(xiàn)了等離子條件下甲烷偶聯(lián)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(fā)現(xiàn)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.基于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
