Edit menu bar aids in Zone A of the menu bar, as shown in Figure 2.1.12 contact angle of water droplets angle measurement meter contact angle measurement aids in Figure 2.1.12 A region of the menu bar to view the menu bar, as shown in Figure 2.1.13 energy conservation smashed stone drops angle measurement increases the surface of the stone can Dongguan droplets angle measurement, 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 droplets of different angles price, 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 surface electronic states within the wave function only exists in the surface area of ??a few atomic layers, while further inside, the wave function decays rapidly. From the bond model, the surface level of surface atoms originated in outward direction has unsaturated bond, known as dangling bonds.
