浮法玻璃是一种重要的商用玻璃，构成了现代建筑和车辆用平板玻璃的主体。表面层的化学计量不同于本体的化学计量，并且通常会由于随后的高温工艺步骤或水或湿气的侵蚀而改变。用离子束分析方法研究了玻璃样品。用共振核反应分析（15N技术），氢浓度分布已被确定。重玻璃成分，特别是钠和锡的配置文件，已获得RBS。报告了随后的温度处理（高达700°C）和受控水合处理引起的浮法玻璃表面组成的变化。氢的吸收和释放的可能机制进行了讨论。
Floatglass is an important kind of commercial glass, comprising the main body of modern flat glass used in buildings and vehicles. The stoichiometry of the surface layer differs from that of the bulk and will usually change due to subsequent high-temperature process steps or attack by water or humidity. Glass samples have been investigated by means of ion beam analysis. Using resonant nuclear reaction analysis (15N technique), hydrogen concentration profiles have been determined. Profiles of the heavier glass constituents, especially sodium and tin, have been obtained by RBS. Changes in the composition of the floatglass surfaces caused by subsequent temperature treatment (up to 700°C) and by controlled hydration treatment are reported. Possible mechanisms of hydrogen uptake and release are discussed.
