主　　题：Squeeze flow Bi-viscosity fluid Rigid spheres Wall slip 

摘      要：In this paper,the squeeze flow between two rigid spheres with a bi-viscosity fluid is *** on lubrication theory,the squeeze force is calculated by deriving the pressure and velocity *** results of the normal squeeze force are discussed,and fitting functions of the squeeze and correction coefficients are *** squeeze force between the rigid spheres increases linearly or logarithmically with the velocity when most or part of the boundary fluid reaches the yield state,***,the slip correction coefficient decreases with the increase in the *** investigation may contribute to the further study of bi-viscosity fluids between rigid spheres with wall slip.
