【摘要】 本文研究了Ｒ２Ｏ（ＲＯ）－Ａｌ２Ｏ３－Ｂ２Ｏ３－ＳｉＯ２系光色玻璃基础组成、结构因子［Ψ］与光色玻璃饱和变暗透射率（ＴＤ）的温度系数ｆ（ＴＤ）（简称温度系数）的相互关系．研究结果表明，光色玻璃的温度系数ｆ（ＴＤ）随结构因子［Ψ］的变化具有一定的规律性．随着结构因子［Ψ］的增大，即当［Ψ］＝０．２８～０．３５时，光色玻璃的温度系数ｆ（ＴＤ）出现了较小值．根据以上结果，探索并研制出了具有较好光色性能即较小温度系数ｆ（ＴＤ）值的玻璃新材料．更多还原

【Abstract】 The relationship was studied among basic composition, structural factors [Ψ] and temperature coefficient f(TD) of saturated darkening transmission (TD) in R2 O (RO ) -A12O3 - B2O3 - SiO2 system photochromic glass. It shows that temperature coefficient f(TD) is relsted to structural faCtors. When [Ψ]=0.28￣0.35,temperature coefficient f(TD) gets to its minimum. According to the above result, a new material with excellent photochromism i.e. less temperature coefficient f(TD) can be obtained.更多还原
