摘要：
The Doi and Ohta theory of the rheology of immiscible blends is extended by considering the field of the velocity with which the interface moves as an independent state variable. This type of generalization is needed in order to be able to take into account the difference in the rheological properties of the fluids involved. Expression for the extra stress tensor as well as equations governing the time evolution of the interfacial area, orientation of the interface and its velocity are derived.
