The changing law of retention index with temperature from chromatographic thermal function resulted from the variation of the different entropy and enthalpy during the chromatographic separation.

并从色谱热力学函数分析了保留指数随温度变化规律的主要原因是由于在色谱分离过程中不同的熵变和焓变所造成的。

So it represents not only a compromise between the power output and the entropy generation rate but also one between the power output and the thermal efficiency.

因此，生态学目标函数不仅反映了输出功率和熵产率之间的最佳折衷，而且反映了输出功率和热效率之间的最佳折衷。
