Originální abstrakt

Presented paper is focused on setting up question of an adhesive force between a solid surface and a liquid, especially in liquid movement dependence. Nowadays is generally supposed, that the real liquid cleaves on the surface so, that the relative velocity of the liquid on the surface is zero. This condition doesn't obtain for the partly wet table and non wet table materials. In this case isn't the adhesive force so large to the absolute cleaving of the liquid on the surface. It is shown in the paper that the adhesive force for the different types of surfaces (glass, Teflon, steel) has dramatically changed. The experiment is looking for the wall angle which starts the movement of the promptly defined drop in its gravity dependence. This angle characterizes the adhesive force similarly as the wet table angle the surface tension. From the experiment is obvious, that the adhesive force for example the rustles steel material for example on the Teflon surface. For the adhesive force is except of the experiment derivate an expression, that puts together the irreversible stress vector and the liquid velocity vector on the runaround surface.
