perfect gas

基本解釋

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.
本文指出混合理想氣體的熵公式不適用于同種氣體，從而對吉布斯佯謬給出了一種解釋。
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.
本文以理想氣體的行為為手段引出熵函數，并以熱力學第一定律為基礎，論證了熵增大原理。
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.
本文研究了理想氣體的帶線性退化阻尼項的可壓縮歐拉方程組的真空初值問題。

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.
