论文摘要
通过使用最近配制的Legendre转换方法对带电系统的热力学方法，我们探讨了Voorn-Overbeek型理论中筛选长度的一般形式，在理想气体形式不给予Debye-Huckel理论中的理想气体形式不给出熵的情况下，这也仍然有效。筛选长度与Flory-Huggins和Voorn-Overbeek类型的自由能Ansatz中的非电压项一致，这些理论源自Legendre Transform的局部曲率特性，其行为与经常被调用的Debye筛选长度明显不同，尽管它在某些有限的案例中降低了。
By using the recently formulated Legendre transform approach to the thermodynamics of charged systems, we explore the general form of the screening length in the Voorn-Overbeek type theories, that remains valid also in the cases where the entropy is not given by the ideal gas form as in the Debye-Huckel theory. The screening length consistent with the non-electrostatic terms in the free energy Ansatz for the Flory-Huggins and Voorn-Overbeek type theories, derived from the local curvature properties of the Legendre transform, has distinctly different behavior than the often invoked standard Debye screening length, though it reduces to it in some limiting cases.
