サバテサイクル
仕事: W = Q 1 − Q 2 = m c v T 1 { [ α − 1 + κ α ( σ − 1 ) ] ε κ − 1 − ( α σ κ − 1 ) } {\displaystyle W=Q_{1}-Q_{2}=mc_{v}T_{1}\{[\alpha -1+\kappa \alpha (\sigma -1)]\epsilon ^{\kappa -1}-(\alpha \sigma ^{\kappa }-1)\}}
熱効率: η = 1 − Q 2 Q 1 = 1 − 1 ε κ − 1 ( α σ κ − 1 ) [ α − 1 + κ α ( σ − 1 ) ] {\displaystyle \eta =1-{\frac {Q_{2}}{Q_{1}}}=1-{\frac {1}{\epsilon ^{\kappa -1}}}{\frac {(\alpha \sigma ^{\kappa }-1)}{[\alpha -1+\kappa \alpha (\sigma -1)]}}}
