| 摘 要： | 本文简要介绍Robertson引入的、适用于非线性区(远离平衡状态)的广义正则统计算符,并给出非平衡态熵的表式。着重运用广义正则统计算符简洁、明了地推证了非平衡热力学中的两个重要定理:最小熵产生定理和超熵判据判据公式。在推导过程中,仅作了局域平衡的假定。

| Abstract: | The present paper gives a brief introduction to the generalized canonical statistical operator used by Robertson and suitable for nonlinear range far away from the equilibrium state and proposes an entropy expression of non-equilibrium as well. By using chiefly the generalized canonical statistical operator two important laws have been simply and clearlyderived in thermodynamics on the basis of a supposition of local equilibrium only: the theorem of minimum entropy production and the expression of excess entropy criterion, |
