25年前，如果不考虑声学和对速度小于声速的稳态运动（当流动类似于液体流动时）的研究，我们对气体动力学的了解可以用几十页纸来阐述。从那时起，而且自1943年以来更快，这个主题已经发展成为一个没有一本书可以完整描述的主题。主要的刺激因素是飞机速度的提高;但第二个刺激因素，即纯科学工作者迟来的认识，即这些现象与经典物理学的现象有着令人着迷的差异，也变得同样重要。
TWENTY-FIVE years ago what was known on the dynamics of gases, if acoustics and the study of steady motion at speeds small compared with that of sound (when the flow resembles that of a liquid) be omitted, could have been expounded in a few dozen pages. Since then, and more rapidly since 1943, the subject has grown into one which no single book can describe in its entirety. The primary stimulus was the increase in aircraft speeds ; but a secondary stimulus, the belated realization of workers in pure science that the phenomena show fascinating differences from those of classical physics, has become equally important.
