isolated system

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

(physics) A system that does not interact with its surroundings. Depending on context this may mean that its total energy and/or momentum stay constant. In thermodynamics, isolated is usually used to indicate that the system's energy does not change. In mechanics it is used to indicate that the system's momentum does not change.

日本語の意味

物理学における「isolated system」とは、外界（周囲）との相互作用が全くない系を指す。つまり、系内部のエネルギーや運動量が外部とのやりとりを行わず、一定に保たれる（熱力学ではエネルギー、力学では運動量が保存される）状態の系である。
