Detailed Product Description: | Surface energy is the creation of material damage the surface of the intermolecular bond measure. In solid state physics theory droplets angle, surface atom having more energy than the material inside the atom, therefore, according to the principle of minimum energy, atoms tend to spontaneously substance rather than the interior surface. Another definition of the surface energy, the material surface with respect to the inner material of the extra energy. Define new power-generating unit surface area made: y = dw / ds substance surface material having a surface tension σ, at constant temperature and pressure under reversibly increase the surface area dA, you need to power σdA droplets angle measurement, because the required power Mixture of equal free energy increases, and this increase is due to an increase in surface area due Mixture, it is known as the surface free energy or the surface energy. Energy conservation smashed stones, stone increases the surface energy, but at the same time you have done the work, energy is conserved. Chemistry, University explained that the surface layer of molecules more than the internal part of the energy molecule known as surface energy. Surface level: the crystal of the original three-dimensional periodic interrupts electron levels are formed at the surface, also known as surface states. Special properties due to the surface potential and the surface layer of the three-dimensional crystal in the interior of the electron which is different electronic states to exhibit special properties. Theoretically, often the traditional band calculation method (see band theory) is applied to the surface of a thin layer, in order to calculate the electron energy and wave function. Description of the wave function of the surface electronic states exist only a few atomic layers of the surface area of ??Dongguan angle meter drops, drop angle measurement, the wave function decays rapidly when further inside. From the bond model, the surface level of surface atoms originated in outward direction has unsaturated bond, known as dangling bonds. Dongguan droplets drops corner angle _ _ ShengDing instruments provided by the Dongguan Sheng Ding Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) (www.dgshengding.com) strong, credible, in Dongguan, Guangdong specialized instrumentation industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead ShengDing instrument and you hand into the brilliant, for a better future! |
