这是一篇工艺试验小结。作者系我院毕业学生。他试图从玻璃结构和碱性作用两方面解释用玻璃粉抛光的机理。对此问题,目前尚未见到国内外有关文章。此文经我院光学工程系郭乐群老师准荐,现予刊登,以期引起大家对抛光机理问题的研讨。 This is a summary of the process test. The author is a graduate student in our hospital. He attempted to explain the mechanism of polishing with glass frit both in terms of glass structure and alkaline action. To this issue, at home and abroad have not yet seen the relevant articles. This article by the Department of Optical Engineering Guo Lequn teacher recommended, is now published, with a view to arouse the discussion on the issue of polishing mechanism.
