在同一性质的复杂系统和简单系统之间存在着熵值差——熵势。

There is an entropic margin, namely entropic potential energy, between complicated system and simple system if they have same property.

目前对传热效果的评价存在熵产最小化和势容耗散取得极值两种不同的准测。

At present, entropy generation minimization and potential capacity dissipation extremum are the two principles to value heat transfer performance.

数值计算和理论分析的结果表明，根据最小传递势容耗散原理得到的结果优于最小熵产原理得到的结果。

The numerical and analytic results show that the heat transfer rate obtained by potential capacity dissipation minimization is better than that by entropy generation minimization.
