介绍性发言。如前一章所述，要讨论悬浮颗粒对液体粘度的影响，就必须考虑这些颗粒运动的数学理论。这个问题在现有文献中受到了很大的关注，除了爱因斯坦和杰弗里的经典著作以及各种附属论文之外，必须提到最近由古斯和马克在《自然科学研究》（Ergebnisse der exakten Naturwissenschaften）1）中以及古斯和其他人在《KolloicUZeitschrift》2）中发表的一系列论文中所作的评论。尽管如此，委员会认为最好在本报告中插入一些数学计算的说明，因为似乎可以以更直接的方式提出理论所涉及的某些要点。与此同时，一些细节发生在古斯的文件第5号，可以处理有些不同，和数值评估的各种公式已被添加。进一步的讨论已经给出的信息，可以从一些实验研究的结果，已发表在最近几年，特别是签署的工作。
Introductory remarks. As stated in the preceding Chapter, p. 97, a discussion of the influence of suspended particles upon the viscosity of a liquid requires the consideration of the mathematical theory of the motion of such particles. The subject has received much attention in the existing literature, and apart from the classical work by Einstein and by Jeffery and from various subsidiary papers, mention must be made of the reviews which recently have been given by Guth and Mark in the “Ergebnisse der exakten Naturwissenschaften” 1), and by Guth and others in a series of papers which have appeared in the ‘‘KolloicUZeitschrift’’ 2). Nevertheless the Committee has considered it desirable to insert an account of some of the mathematical calculations into the present Report, as it seemed possible to arrange the matter in a form which brings out certain points involved in the theory in a more direct way. At the same time a few details which occurred in Guth’s paper no. 5, could be treated somewhat differently, and numerical evaluations of various formulae have been added. Further a discussion has been given of the information that can be derived from the results of some experimental investigations which have been published in recent years, in particular of Signer’s work.
