模型理论

The steady model is able to predict the start and the end points of the phase inversion, although the model parameters have no distinct physical meanings. The factors, such as agitation strength, density, viscosity, interfacial surface tension, grafting efficiency and volume fraction etc., have been considered in the dynamic model, which can predict the start point of phase inversion successfully.
