For these cases, Onsager and others formulated a theory of nonequilibrium thermodynamics and showed that the second law continues to hold. 針對這類(lèi)狀況，昂薩格等人提出了非平衡熱力學(xué)理論，并證明熱力學(xué)第二定律依然有效。
Based on a thermodynamic model of gas_liquid equilibrium, the variation of phase behavior in a volatile oil system during gas injection has been investigated. 根據氣液兩相相平衡熱力學(xué)模型研究了某揮發(fā)油油藏在注天然氣過(guò)程中油藏體系相態(tài)特征的變化規律。
