多了substituted这词,感觉翻译混乱了? the process is applicable to making aromatic and heterocyclic substituted monoolefins and aliphatic diolefins. 该工艺应用于生产芳烃单烯烃及杂环单烯烃和脂族二烯. aromatic monoolefin + heterocyclic substituted monoolefin = monoolefins (复数的原因) 不过,不知道aromatic monoolefin 是否就是芳烃,感觉不像.请内行指点. substituted指杂环(heterocyclic) 取代苯环(aromatic为苯环)查看更多
化学反应速率方程讨论? 下面的英文来自英文原版书籍,中文是我自己翻译的。红色文字部分是我不能肯定的地方,大家帮忙看看有什么错误或提出更好的译文,如发现其他部分不妥或错误,也请直言。 the rate form of eq. 57 and some of its generalizations are used to represent a number of widely different kinds of reactions . for example, in homogeneous systems this form is used for enzyme-catalyzed reactions where it is suggested by mechanistic studies (see the michaelis-menten mechanism in chap. 2 and in chap. 27). it is also used to represent the kinetics of surface-catalyzed reactions. in mechanistic studies, this form of equation appears whenever the rate-controlling step of a reaction is viewed to involve the association of reactant with some quantity that is present in limited but fixed amounts ; for example, the association of reactant with enzyme to form a complex, or the association of gaseous reactant with an active site on the catalyst surface. 用 57 式及其的某些推广式 表示的反应所涵盖的类型差别大,数量多 。例如,机理研究推荐在均相体系中用这个表达式来表征酶催化反应(参考第二章和第二十七章的米 - 门机理)。再如,它也用于表征表面催化的反应动力学。 在机理研究中,任何一个速率控制步骤中的反应物如果被认为发生了有限数量的缔合作用,则会使用这个速率表达式 ;例如,反应物与酶缔合生成某种化合物,或气体反应物在催化剂表面上的活性部位 发生的缔合作用。 查看更多
