adiabatic

IPA（発音記号）

/ˌeɪdaɪəˈbætɪk/

形容詞

比較不可 過程

(physics, thermodynamics, of a process) That occurs without gain or loss of heat (and thus with no change in entropy, in the quasistatic approximation).

日本語の意味

形容詞：熱力学において、断熱過程を示す。具体的には、系が熱エネルギーの出入り（吸収または放出）を伴わず、結果として準静的近似下ではエントロピーに変化がない状態を指す。

The scientist carefully designed the experiment so that the gas underwent an adiabatic compression.

科学者は実験を慎重に設計し、気体が熱の出入りのない圧縮を受けるようにした。

意味（1）

(physics, thermodynamics, of a process) That occurs without gain or loss of heat (and thus with no change in entropy, in the quasistatic approximation).

The line drawn on the indicator diagram in the latter case has been named by Professor Rankine an Adiabatic line, because it is defined by the condition that heat is not allowed to pass through (διαβαίνειν) the vessel which confines the substance.

意味（2）

(physics, quantum mechanics, of a process) That involves the slow change of the Hamiltonian of a system from its initial value to a final value.

In this section we examine the limiting cases when T is very small (sudden change) and very large (adiabatic change).
