讨论和澄清了阴极析氢动力学领域中一些概念和机理上的突出问题。对假定无机理的动力学方程进行了充分的推导和关联，揭示了几个参数的表达式，这些参数采用一种或多种机理特有的方法。使用统计方法处理数据证明是不可或缺的估计这些参数的值。确定析氢反应机理的另一种方法是检查各个反应路径的动力学，以便可以推导出所有路径的参数的期望值。因此，在酸性和碱性溶液中的一些重要的机制处理，并显示出可区分的实验。利用已经发表的数据，计算了在汞、银、镍和光滑铂阴极上发生各种反应途径的实际条件。它不仅可以将这些推导的数据与观察结果进行比较，从而验证特定反应路径的发生，而且可以在特定情况下证明某些机制的不可能性。上述方法的最新进展已成为可能的讨论有关的数据最近已成为可利用的。
Some of the outstanding problems of concept and mechanism in the field of cathodic hydrogen evolution kinetics are discussed and clarified. A full derivation and correlation of kinetic equations which assume no mechanism reveals expressions for several paranmters which take wflues specific to one or more mechanisins. The use of statistical methods of treatment of data proves indispensible in estimating the values of these parameters. A further method of ascertaining the mechanism of the hydrogen evolution reaction is to examine the kinetics of the individual reaction paths, so that the expected values of parameters conmmn to all paths may be deduced. A number of mechanisms important in acid and alkaline solulions are thus treated, and are shown to be distinguishable experimentally. Using already published data, the actual conditions under which various reaction paths take place at mercury, silvcr, nickel, and smooth platinum cathodes are calculated. It is not only possible to compare these deduced data with observation, and thereby verify the occurrence of a particular reaction path, but also to denmnstrate the impossibility of some mechanisms in specific cases. The recent advances which the foregoing methods have made possible are discussed in relation to data which have recently beconm available.
