杜絕機譯,我看已有翻譯還不到位,請樓主審閱
By the 1880s,however,instrialists were beginning to
recognize that the scaling up of consultants』 laboratory preparations and syntheses was a distinctly different activity form laboratory investigation. They began to refer to this scaling problem and its solution as 「chemical engineering」-possibly because the mechanical engineers who had already been introced into works to maintain the steam engines and pumps in an instry of growing complexity were the very men who seemed best able t o understand the processes involved.
可是,到19世紀80年代,企業家開始認識到,顧問們的實驗室制備和合成的規模化擴大是一個與實驗室研究完全不同的活動。他們開始把這個規模化擴大的問題及其解決辦法稱之為「化學工程」,這可能是因為機械工程師在一個日趨復雜的行業中維護蒸汽機和泵浦已經發揮了作用,而他們正是似乎最能了解所涉及過程的人。
說明:翻譯要忠於原文,只能翻到這樣。但意思是說:實驗室研究和規模生產區別很大,這個規模市生產的問題和方法就稱為化學工程,它的起因可能來自於機械工程,因為機械工程師們,他們在日趨復雜的機械行業中為維護蒸汽機、泵浦而發揮了作用,他們也是最了解這個過程的人。

氧化還原電位和Ce3 +的/價鈰氧化還原硫酸鈰在硫酸溶液中的反應和溶解性動力學
摘要
實驗工作是用評估價鈰+ / Ce3 +的氧化還原電對在硫酸電解液在氧化還原液流電池( RFB )技術使用的目的進行的。鈰硫酸鹽在0.1-4.0 M硫酸在20-60 ℃時的溶解度進行了研究。觀察兩者的硫酸濃度和溫度對硫酸鈰的溶解性的協同效應。硫酸鈰的溶解度用硫酸和溫度上升的上升濃度顯著降低,而硫酸鈰中的溶解度會經過一個顯著最高在40℃下氧化還原電勢和酸鈰/二氧化鈰的氧化還原反應的動力學相同溫度濃度條件下也進行了研究。氧化還原電位,用合成的氧化還原電極( Pt-Ag/AgCl )等摩爾價鈰/ Ce3 +的硫酸電解質溶液(即[ Ce3 +的] = [價鈰] )測得。該Ce3 +的/ Ce4 +離子的氧化還原電位顯著降低(即移位到更負的值)與上升的硫酸濃度;小最大值在40℃下觀察到的循環伏安實驗證實了Ce3 +的/價鈰氧化還原對玻碳電極在硫酸溶液反應( CGES )的慢電化學動力學。溶解度,氧化還原電位和硫酸濃度Ce3 +的/ Ce4 +離子的氧化還原反應的動力學的觀察依賴關系被認為是兩個氧化還原物質由硫酸根陰離子的不等價絡合的結果是:高鈰離子被更強烈地結合到硫酸比的就是鈰離子。最佳溫度濃度條件,為RFB電解質似乎是40°C和1M硫酸,其中兩個鈰物種的相對良好的溶解性,被發現的最大氧化還原電位的,和CGE S中的更多或更少的令人滿意的穩定性。即使如此,鈰鹽在硫酸介質和Ce3 +的/ Ce4 +離子的氧化還原在碳反應的緩慢氧化還原動力學的溶解度相對低表明Ce3 +的/ Ce4 +離子可能不會非常適合於在RFB技術的使用。
