perfect gas

基本解释

This paper puts forward that the Entropy Formula of the Mixed Perfect Gas doesn t apply to pure gas, and gives a kind of explanation about Gibbs paradox.
本文指出混合理想气体的熵公式不适用于同种气体，从而对吉布斯佯谬给出了一种解释。
The state function, entropy, is introduced by the means of a perfect gas behavior, and the second law of thermodynamics is demonstrated based on the first law.
本文以理想气体的行为为手段引出熵函数，并以热力学第一定律为基础，论证了熵增大原理。
The Cauchy problem of Euler equations with degenerate linear damping for a perfect gas is studied in this paper, while the initial gas lies in a compact domain.
本文研究了理想气体的带线性退化阻尼项的可压缩欧拉方程组的真空初值问题。

But the gas-seals would be perfect if the pistons were liquid rather than solid.
ECONOMIST: An engine made of water
In fact, it's not far-fetched to imagine a perfect storm in which low-priced oil coincides with climbing natural gas prices just as a drought hits the Midwest, ravaging the corn crop.
FORBES: Ethanol Gusher!
If the fuels were perfect substitutes, oil prices would thus tend to be about 6 times natural gas prices.
