氟化效率 的英文怎麼說
中文拼音 [fúhuàxiàolǜ]
氟化效率
英文
fluorine efficiency-
According the ftir results, poh shifts to higher wavenumbers with increased fluorine content in the fha phases, which meant in the fha phase the fluorine existed as f - oh chains, it can be concluded that fha phase obtained is actually ha / fa solid solution
研究發現，三種含氟化合物都能夠有效地在產物中引入氟形成fha相或fa相。其中， cf3cooh的引氟效率較低，只有1 3左右。 hpf6禾nh4pf6貝有較高的引氟效率。In the thesis, we proposed a random lattice model of mea the lattice model randomly occupied by three kinds of particles, pt / c, nafion and ptfe ( poly - tetra - fluoro - ethylene ), was generated on a computer by the means of monte carlo method. it was supposed that current was only produced on those catalysts which have not only channels of electrons via carbon but also have channels of proton via nafion. the purpose of the work, in a word, is to find how many catalysts, pt / c, with such a two - types channels
本文首先建立了質子交換膜燃料電池的膜電極的隨機方格子模型，在電極模型各格點位置用montecarlo方法生成隨機分佈的電極粒子、 nafion粒子和聚四氟乙烯團粒，認為只有那些既有質子傳輸通道，又有連續的電子通道和氣體擴散通道的胞元才產生有效的電流，而其餘胞元不產生電流，把電極的輸出電流轉化成一個概率事件。New york ( reuters health ) jan 15 - for chemotherapy - naie adanced oarian cancer patients, gemcitabine plus carboplatin yields response rates comparable to that of paclitaxel plus carboplatin, with a " more acceptable toxicity profile, " researchers from singapore report
紐約（路透社健康專欄） 1月15號訊-新加坡的研究人員報告說，用化學療法治療晚期卵巢癌， 2 ， 2 -二氟脫氧胞嘧啶核苷聯合卡鉑治療出現的有效率可與紫杉醇聯合卡鉑的治療結果相比，而且有「更可接受的毒性資料」 。
