摘要
将触变性流体作为一种固－液二相体，给出了流体触变性的一种新解释．通过简单分析，得到触变性流体本构方程中结构参量λ和其中各参数的物理意义．λ为流体内部结构变形张量的一个标量值函数速率方程中重建速率系数与结构的弹性常数有关．
A new explanation on the thixotropy of fluid was provided, in which the thixotropic fluid was considered to have the two-phase structure of solid and liquid. After a brief discussion, the physical meanings of the structural parameter λ and some constants in the constitutive equations of thixotropic fluid were showed, which λ was a scalar function of the deformation tensor of the structure in the liquid and the build-up rate constant depended on the elasitc properties of the structure.
