论文摘要
我们讨论了包含胶体颗粒的稳定电解质中Seebeck效应的特殊性。它的不寻常特征是两个阶段字符,差分热电器的线性增加是胶体颗粒浓度的功能$ n _ {\ odot} $在第一阶段,并且在第二个(稳定状态)的小$ n _ {\ odot} $中急剧下降。我们表明,初始状态的性质受稳定电解质介质本身的移动离子的热扩散流以及胶体颗粒在大部分悬浮液中的形成中的形成。在热电效应中,稳态的细节归因于在缓慢的热扩散过程中大量胶体颗粒的大量位移,并且在电极附近分解了电负性。
We discuss the peculiarities of the Seebeck effect in stabilized electrolytes containing the colloidal particles. Its unusual feature is the two-stage character, with the linear increase of differential thermopower as the function of colloidal particles concentration $n_{\odot}$ during the first stage and dramatic drop of it at small $n_{\odot}$ during the second one (steady state). We show that the properties of the initial state are governed by the thermo-diffusion flows of the mobile ions of the stabilizing electrolyte medium itself and how the colloidal particles participate in formation of the electric field in the bulk of suspension. In its turn the specifics of the steady state in thermoelectric effect we attribute to considerable displacements of the massive colloidal particles in process of their slow thermal diffusion and break down of their electroneutrality in the vicinity of electrodes
