From the view of fluid mechanics, the shear-free air water interface corresponds to a slip boundarycondition in fluid and relatives to the concept of effective slip length.
从流体力学的角度来看，这个无剪切界面对应着流体中的滑移边界条件，而与此相关的概念是有效滑移长度。

The motion of phase interface, the temperature distribution and the thermal storage time of the cool storage slab under the first boundarycondition were obtained.
A new stress element near a hole which satisfies both the stress boundary conditions at the hole and at the surface of the laminate and stress continuity condition at the interface is developed.
