文摘Through the analysis of the present situation of the rheology of suspension disperse systems, the classical Einstein′s viscosity law was developed into the generalized Einstein′s viscosity law which can be further developed into universalized form, called the universalized Einstein′s viscosity law by introducing modification function f(φ) . Some rational forms of the function f(φ) were discussed according to functional approximation method, and were consequently developed into a few suspension disperse system rheological equations suitable for high particle concentration. These equations all keep good consistence with the models acquired in experiments or other mathematical physics analysis.
