Reversible and irreversible thermodynamics, kinetics, quantum mechanics, and statistical thermodynamics are the roots of the described thermal analysis.
可逆和不可逆的热力学，动力学，量力学和统计热力学是被描述的热分析的根。

The theoretical analysis on bubble mass transfer process was made by the non reversiblethermodynamics. Non steady state, steady state and equilibrium state and changing regulation were discussed.
运用不可逆热力学原理，对气泡传质过程进行了理论分析，讨论了非稳态、稳态、平衡态的差异及其变化规律。
