| 摘 要： | 为得到普遍化的Clausius不等式，通过引入附加项，将原不等式由封闭系统推广到任意系统。讨论了该不等式与几个重要热力学判据的关系。以稳定流动系统为例，用所提出的Clausius不等式计算电功。并将计算结果与传统计算方法进行比较，结果表明所提出的Clausius不等式是正确的。

| Abstract: | To generalize the Clausius inequality, by introducing an additional term, the original Clausius inequality for closed systems was extended to a universal inequality for open systems. Relationships between the inequality and important thermodynamic criteria were discussed. The electrical work was calculated for steady state flow systems using the Clausius inequality derived. The results are compared with traditional results to verify the universal inequality. |
