今年二月发表的“关于饱和汽压的实验”一稿我还有几点修改和补充一下: 一、文中有关“道耳顿定律的实验”,曾介绍读者使用水和乙醚作为试液,因为它们相互混溶量极少。可是水和汽油的混溶量更少,在长玻璃管水银柱上端体积很小的情况下,使用水和汽油较为可靠。二、由于各种原因,难免使玻璃管中存在 There are a few changes and additions to the manuscript on “experiment on saturated steam pressure” published in February this year: 1. The article on “Experiments of Dawley’s Law” introduced the reader to use water and ether as the test solution because They are extremely miscible with each other. However, the miscibility of water and gasoline less, in the long glass tube mercury column volume is very small, the use of water and gasoline is more reliable. Second, due to various reasons, it is inevitable to make glass tube exist
