The method of atomic force microscopy explores a roughness surface the silica glass cooled with different velocity from temperature 2300 °C. It is compared two modes cooling rods diameter 16mm: convective heat exchange surrounding air and quenching dropping sample into vessel water. in second mode was essentially less that can promote magnification its strength. results these studies may turn o...

Presented research is devoted to solving the problem of treatment complex glass relief surfaces by mechanical vibration grinding. The dependences obtained grinding results on type surface, grain size and parameters are investigated. Results: Mathematical change in light transmission ground surface pattern, obtained.
