报告摘要：Onsager principle is the variational principle proposed by Onsager in his celebrated paper on the reciprocal relation. The principle is useful not only in deriving many evolution equations in soft matter systems, it is also useful in solving such equations approximately. Three examples are discussed: the capillary filling, the stratification in binary colloidal solutions, and the dynamics of viscoelastic filaments. These examples show that the present method is novel and gives new perspective of the essential dynamics in soft matter systems.
