本文提出了定态热力学过程的一个新原理：定态过程中局部熵产生的最大值变为最小值。为了说明该原理的实用性，我们考虑了单原子气体中的一维稳态传热。在这里，我们解决扩展的时刻计划，从玻尔兹曼方程。这样的计划需要考虑的所有时刻的边界条件，这些都是通过新的原则。此外，我们表明，在这种情况下，全局熵产生的最小原理不会导致良好的结果。[S0031-9007（98）06306-6]
In this paper we propose a new principle for stationary thermodynamic processes: The maximum of the local entropy production becomes minimal in stationary processes. In order to show the usefulness of the principle, we consider one-dimensional stationary heat transfer in monatomic gases. Here we solve extended moment schemes that follow from the Boltzmann equation. Such schemes require boundary conditions for all moments under consideration, and these are constructed by means of the new principle. Moreover, we show that the minimum principle for the global entropy production does not lead to good results in this case. [S0031-9007(98)06306-6]
