Survey of the Physical Basis of Some Glass Properties,new glasses. In most cases, relations between composition and properties were established entirely on an empirical basis. One was forced frequently to introduce one, two, or more constants into equations describing these relations in order to obtain better agreement with experimental data.温室 发表于 2025-3-25 13:08:24

,Grundzüge der angewandten Hygiene, surface, e. g., in a volcanic eruption; and, when cooled quickly, the foaming melt became a solid natural glass foam, since high viscosity prevented the escape of bubbles. Modern industrial technologies may be considered variations of this basic process.凹室 发表于 2025-3-25 21:10:27

Karen Blixen und Heinrich Heineerted to thermal vibration; another part, however, contributes to the passing light by emission. This emission is caused by the return of excited electrons to their original level. This part does not conform exactly to the wavelength of the light absorbed.公猪 发表于 2025-3-26 20:23:24
