结果表明，混合过程中存在三种成分：对流、扩散和剪切。研究了分析完全混合物和部分混合物所涉及的概念，并为混合物的状态发展了一个统计上令人满意的表达式。考察了多种混合速率理论，并与已发表的少数实验结果进行了比较，提出了一种基于扩散理论的新的理论处理方法。这至少与现有理论一样符合事实，并为推广到更复杂的情况提供了更好的基础。
It is shown that there are three components in a mixing process: convection, diffusion and shear. The concepts involved in analysing complete and partial mixtures are examined and a statistically satisfactory expression evolved for the state of a mixture. A number of theories of mixing rate are examined and compared with the few published experimental results, and a new theoretical treatment is offered based on diffusion theory. This is shown to be in at least as good agreement with fact as existing theories, and to provide a better basis for extension to more complex cases.
