摘　　要：使用表面显微镜分析高硼硅酸盐玻璃表面发毛现象,测试了保温时间、保温温度、多次热历史及化学成分对高硼硅酸盐玻璃抗水性能的影响。结果表明:长时间、较高温度、多次热处理都可能发生分相,造成抗水性能大大降低;在高硼硅酸盐玻璃中引入0.1%左右的Li2O代替Na2O可以大大减少分相倾向,提高玻璃的抗水性能。The microscope is used when analyzing the crawling phenomenon of borosilicate glass, and it is tested how heat-retaining time, heat-retaining temperature, heat history, and the chemical components have effects on its anti- moisture performance. As a result, long time, high temperature, and repeated heat treatment may cause separation, lowering the performance greatly. 0.1% of Li2O instead of Na20 introduced into the glass may decrease the tendency of separation and improve the anti-moisture level.
