“mean free path”的概念、定义、翻译、参考文献-科学参考

mean free path

Physics

The average distance travelled between collisions by the molecules in a gas, the electrons in a metallic crystal, the neutrons in a moderator, etc. According to the kinetic theory the mean free path between elastic collisions of gas molecules of diameter d (assuming they are rigid spheres) is 1/√2nπ‎d², where n is the number of molecules per unit volume in the gas. As n is proportional to the pressure of the gas, the mean free path is inversely proportional to the pressure.

Chemical Engineering

The mean distance between successive elastic collisions of molecules in a gas. According to the kinetic theory of gases, the mean free path is inversely proportional to the pressure of the gas.
