我们讨论了禁闭状态下胶体的布朗动力学，特别强调了溶剂动力学的影响。我们回顾了动态密度泛函理论（DDFT）的推导，包括水动力相互作用的某些方面及其在悬浮液微流变学中的应用。我们特别讨论了Stokes定律在悬浮液和非平衡溶剂结构介导的相互作用中的失效。关于水动力色谱，我们还讨论了颗粒在窄通道中的固定输运，以及在这种情况下DDFT失效的原因。
We discuss the Brownian dynamics of colloids in confinement with special emphasis on the influence of the solvent dynamics. We review the derivation of a dynamic density functional theory (DDFT) including some aspects of hydrodynamic interactions and its application to the micro-rheology of suspensions. In particular we discuss the failure of Stokes' law in suspensions and non-equilibrium solvent structure mediated interactions. With regard to hydrodynamic chromatography we also discuss the stationary transport of particles in narrow channels, and the reasons for the failure of DDFT in this situation.
