<p>The present invention relates to a method of analysis of intermolecular forces. The invention comprises preparing a test fixture; placing a drop of water on a surface of block B and causing a circular glass plate on block A to attach to the water film and be pressed into back-and-forth motion; waiting to clearly perceive an increase in frictional force, then forcibly pressing the two blocks together; the external manual pressure, before being released, takes advantage of the water molecules wetting the glass plate as well as the fluidity of the water molecules, making the nominal contact area and the actual contact area of the water molecules of the adhesion layer equal and in full contact; after release of the external manual pressure and under forces such as ambient atmospheric pressure, the two blocks A and B are together and the interface thereof is considered to be an ideal interface; while still in accordance with the conditions of equilibrium of an object, obtaining, by means of experimental analysis of changes in load conditions of block A during the evacuation process, the macroscopic manifestation of the size of the molecular force and the displayed form of the resilient frictional force, and verifying the qualitative relationship between microscopically manifested molecular forces and intermolecular distance and inferring the relationship existing between molecular forces and intermolecular distance.</p> |
