Following Onsager (1931,I), let us extend our considerations to thermodynamically non-equilibrium systems. As a basis, we need locally defined versions of the extensive macroscopic quantities <math>U</math>, <math>V</math> and <math>N_i</math> and of the intensive macroscopic quantities <math>T</math>, <math>p</math> and <math>\mu_i</math>.

For classical non-equilibrium studies, we will consider some new locally defined intensive macroscopic variables. We can, under suitable conditions, derive these new variables by locally defining the gradients and flux densities of the basic locally defined macroscopic quantities.

Such locally defined gradients of intensive macroscopic variables are called 'thermodynamic forces'. They 'drive' flux densities, perhaps misleadingly often called 'fluxes', which are dual to the forces. These quantities are defined in the article on Onsager reciprocal relations.

这种局部定义的强烈宏观变量梯度被称为“热力学力”。它们“驱动”通量密度,也许常被误称为“通量” ,这是力的双重作用。这些量在关于昂萨格互反关系的文章中定义。
