Width and height measurements: according to the sampling resulting picture, select the leftmost point drop, click and hold the left mouse button, drag the cursor to the right-most point of the water droplets, and then drag the cursor to the highest point of the water droplets release the mouse button, and finally The system according to the fitting of the measured contour data stored in the data storage area. Water droplet contact angle measurement angle measurement artificial tangential contact angle measurement: according to the sampling resulting picture, select the leftmost point drop, click the left mouse button, drag the cursor to the right most point drop, do liquid along the liquid outer contour tangent angle manufacturers droplets, and finally the system according to the tangent to fit the measured data stored in the data storage area. :( Aids aids when applied to concave, convex contact angle test) Click aids, aids into the interface, as shown in 2.1.10 These dangling bonds can provide electronic or absorb water droplets electronic Zhuhai angle, equivalent to the semiconductor donor impurities and acceptor impurities (see Semiconductor), thereby forming a donor level or acceptor level corresponding to the surface level. Surface level can be located in the area of ??physical tape band gap can also be located to allow the band, which is called the resonant states. Clean the surface cleaning surface surface level is called the intrinsic surface states. When changing the surface structure, surface adsorption of foreign atoms, or the presence of various defects of the surface layer, the density and distribution of the surface level will change significantly. Origin of the surface level, the relationship between density and distribution, as well as with the surface structure is one of the basic content of surface physics. The main experimental study of the surface level means there photoelectron spectroscopy, plasma and in the spectrum.
