[求助] 急求翻译!

1.The reaction time/product yield profiles of the nitration of benzene and alkyl derivatives all run linearly with a similar gradient over a wide range of reaction times until the substrates are completely consumed,showing no kinetic dependence of the reaction on the concentration of substrates.
2.The relative reactivities of mono-substituted benzenes such as alkyl- and halogeno-benzenes,phenolic ethers and some acetals are summarized in Table10,together with the respective partial rate factors.
3.Presented in Fig.4 is a Hammett plot of the meta and para values of the partial rate factors versus Brown's σ+ constants.Except for the methoxy group represented by a solid circle ,this plot produces a straight line with a ρ-value of -6.8 and a correlation coefficient r of 0.952.

苯和烷基衍生物的硝化反应的反应时间/生成物产率曲线在直到底物完全耗竭的较宽反应时间范围内均显示为相似斜率的直线,显示反应对底物浓度无动力学依赖性

2.The relative reactivities of monosubstituted benzenes such as alkyl and halogenobenzenes,phenolic ethers and some acetals are summarized in Table10,together with the respective partial rate factors单取代苯类诸如烷基和卤代苯,酚醚和某些缩醛的相对反应性及各自的分速度系数概括在表10中。
