A toy model is used to describe the following steps to achieve the no-reversible-direction axiom in a tutorial manner: (i) choose a state space results in the balance equations on state space which are linear in the process directions, (ii) avoid a reversible process direction that cannot be generated via a combination of non-reversible ones, (iii) process directions that are in the kernel of the balance equations and do not enter the entropy production. The Coleman-Mizel formulation of the second law and the Liu relations follow immediately.
(i) 选择一个状态空间，得到状态空间上的平衡方程，这些方程在过程方向上是线性的；(ii) 避免出现不能通过不可逆方向的组合产生的可逆过程方向；(iii) 处于平衡方程核中且不进入熵产生的过程方向。第二定律的科尔曼 - 米泽尔公式和刘关系立即随之而来。
