摘要：
We propose a mechanism for non-contact repulsive interaction between elastic bodies moving past each other in a fluid. A lateral flow along the curved surface and the resulting deformation lead to dissipative lubrication forces that act normal to the surfaces. Forces between polymer-bearing surfaces undergoing shear are calculated and seem to be important for the interpretation of surface force apparatus measurements such as those by Klein et al.
