This paper develops a non-equilibrium thermodynamic approach to life, with particular regards to the membrane role. The Onsager phenomenological coefficients are introduced in order to point out the thermophysical properties of the cell systems. The fundamental role of the cell membrane electric potential is highlighted, in relation to ions and heat fluxes, pointing out the strictly relation between heat exchange and the membrane electric potential. A Seebeck-like and Peltier-like effects emerge in order to simplify the description of the heat and the ions fluxes. Life is described as a continuos transition between the Peltier-like effect to the Seebeck-like one, and .
本文提出了一种关于生命的非平衡热力学方法，特别关注细胞膜的作用。引入昂萨格现象学系数以指出细胞系统的热物理性质。强调了细胞膜电势相对于离子和热通量的基本作用，指出了热交换与膜电势之间的严格关系。出现了类似塞贝克效应和类似珀尔帖效应，以简化对热通量和离子通量的描述。生命被描述为从类似珀尔帖效应到类似塞贝克效应的连续转变。
