论文摘要
Schottky系统中的非平衡过程是通过投影到平衡子空间可逆的伴随过程中产生的，而非平衡变量是平衡变量的函数。证明了保证随附过程与非平衡熵的兼容性的嵌入定理。非平衡熵定义为在非平衡状态空间上的状态函数，该空间包含接触温度作为非平衡变量。如果熵产生不取决于内部能量，则接触温度也会在非平衡中变化为恒温温度，这一事实允许在非平衡中使用温度作为原始概念。重新审视了耗散不平等，并实现了卡诺过程以外的广义循环过程的效率。
Non-equilibrium processes in Schottky systems generate by projection onto the equilibrium subspace reversible accompanying processes for which the non-equilibrium variables are functions of the equilibrium ones. The embedding theorem which guarantees the compatibility of the accompanying processes with the non-equilibrium entropy is proved. The non-equilibrium entropy is defined as a state function on the non-equilibrium state space containing the contact temperature as a non-equilibrium variable. If the entropy production does not depend on the internal energy, the contact temperature changes into the thermostatic temperature also in non-equilibrium, a fact which allows to use temperature as a primitive concept in non-equilibrium. The dissipation inequality is revisited, and an efficiency of generalized cyclic processes beyond the Carnot process is achieved.
