In the interface aids, divided into Area A - the menu bar, toolbar, Area B, C zone pattern workspace angle of water droplets, D zone status bar. Water droplet contact angle measurement angle measurement contact angle measurement aids in Area A menu bar File menu bar, as shown in Figure 2.1.11 2.1.11 New: to create a new work area. Open: Before opening the sample pictures. Save: Save the current picture pattern workspace. Water droplet contact angle measurement angle measurement surface contact angle measuring instrument is able to create a bond between the molecules on the surface of the material destruction of metrics. In solid state physics theory, the surface atoms have more energy than the internal atomic species, therefore, according to the principle of minimum energy suppliers angle of water droplets, spontaneously tends atoms substance rather than the interior surface. Another definition is the surface energy of the water droplets angle measurement relative to the surface of the material inside the material Dongguan more energy. The decomposition of a solid material into smaller pieces need to destroy the chemical bonds within it drops angle measuring instrument, so consumes energy. If this decomposition process is reversible, so the material is decomposed into small pieces of energy needed to increase the surface of small pieces of material equal to the energy, i.e., the surface energy increases. But in fact, the surface is only just formed in a vacuum is consistent with the above energy conservation. Because the newly formed surface is very volatile, and their surface atoms by the reaction and the inter recombination, or other molecules or atoms around adsorption, so that the surface energy is reduced.
