理想气体自由膨胀中的热辐射效应与经典热力学中的Gibbs Partial
Thermal Radiation Effect in the Free Expansion of an Ideal Gas and Gibbs' Paradox in Classical Thermodynamics
摘要：
理想气体的标准理论忽略了气体粒子与热辐射（光子气体）的相互作用，热辐射填充了它们之间的真空空间。这是一种非物理特性，因为每种材料都会吸收和辐射热能。这种相互作用在气体中可能是重要的，因为后者与固体和液体不同，能够经历明显的体积变化。考虑到这一点使得理想气体的行为更加真实，并消除了吉布斯悖论。
英文摘要：
The standard theory of ideal gases ignores the interaction of the gas particles with the thermal radiation (photon gas) that fills the otherwise vacuum space between them. This is an unphysical feature since every material absorbs and radiates thermal energy. This interaction may be important in gases since the latter, unlike solids and liquids are capable of undergoing conspicuous volume changes. Taking it into account makes the behaviour of the ideal gases more realistic and removes Gibbs' paradox.
