杜绝机译,我看已有翻译还不到位,请楼主审阅
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世纪80年代,企业家开始认识到,顾问们的实验室制备和合成的规模化扩大是一个与实验室研究完全不同的活动。他们开始把这个规模化扩大的问题及其解决办法称之为“化学工程”,这可能是因为机械工程师在一个日趋复杂的行业中维护蒸汽机和泵浦已经发挥了作用,而他们正是似乎最能了解所涉及过程的人。

说明:翻译要忠于原文,只能翻到这样。但意思是说:实验室研究和规模生产区别很大,这个规模市生产的问题和方法就称为化学工程,它的起因可能来自于机械工程,因为机械工程师们,他们在日趋复杂的机械行业中为维护蒸汽机、泵浦而发挥了作用,他们也是最了解这个过程的人。

Molecular spectros is emitted by the molecules are absorbed by the light on the spectral spectrum. He is a measure of the molecular structure, material qualitative, quantitative analysis of important experiment method for nearly three years. For molecular spectros and theoretical research has made good progress. From spectrum can get on the movement of electrons and nucleus of vibration and detailed knowledge of rotation.
Based on the relative molecular spectros theory, a given free NS with samples were analyzed, and through the theoretical calculation and the computer simulation, the precision of free radicals NS spectrum constant

氧化还原电位和Ce3 +的/价铈氧化还原硫酸铈在硫酸溶液中的反应和溶解性动力学
摘要
实验工作是用评估价铈+ / Ce3 +的氧化还原电对在硫酸电解液在氧化还原液流电池( RFB )技术使用的目的进行的。铈硫酸盐在0.1-4.0 M硫酸在20-60 ℃时的溶解度进行了研究。观察两者的硫酸浓度和温度对硫酸铈的溶解性的协同效应。硫酸铈的溶解度用硫酸和温度上升的上升浓度显著降低,而硫酸铈中的溶解度会经过一个显著最高在40℃下氧化还原电势和酸铈/二氧化铈的氧化还原反应的动力学相同温度浓度条件下也进行了研究。氧化还原电位,用合成的氧化还原电极( Pt-Ag/AgCl )等摩尔价铈/ Ce3 +的硫酸电解质溶液(即[ Ce3 +的] = [价铈] )测得。该Ce3 +的/ Ce4 +离子的氧化还原电位显著降低(即移位到更负的值)与上升的硫酸浓度;小最大值在40℃下观察到的循环伏安实验证实了Ce3 +的/价铈氧化还原对玻碳电极在硫酸溶液反应( CGES )的慢电化学动力学。溶解度,氧化还原电位和硫酸浓度Ce3 +的/ Ce4 +离子的氧化还原反应的动力学的观察依赖关系被认为是两个氧化还原物质由硫酸根阴离子的不等价络合的结果是:高铈离子被更强烈地结合到硫酸比的就是铈离子。最佳温度浓度条件,为RFB电解质似乎是40°C和1M硫酸,其中两个铈物种的相对良好的溶解性,被发现的最大氧化还原电位的,和CGE S中的更多或更少的令人满意的稳定性。即使如此,铈盐在硫酸介质和Ce3 +的/ Ce4 +离子的氧化还原在碳反应的缓慢氧化还原动力学的溶解度相对低表明Ce3 +的/ Ce4 +离子可能不会非常适合于在RFB技术的使用。
