中文摘要:

      本文利用高温路融反应及液氮淬冷技术制Li2S─B2O_3体系玻璃采用。IR、Raman振动光谱方法对玻璃的基团结构进行了表征并讨论了基团结构随组成的变化对玻璃稳定性能的影响。实验发现．随Li2S含量增加．玻璃结构经历了由平面网络转变为三维网络．最终离解为孤立的小基团的变化过程。

英文摘要:

      Li_2S-B_2O_3 system glass samples were obtalned by high- temperature melting reaction andfast cooling technigue with liguid nitrogen. The unit structure of the glass samples wascharacterized with IR and Raman spectra,and the relationship between unit structure variationand glass stability was discussed. The experlmental results indicate that the glss structure wouldchange from plainner network to trimentional network,and ultimately break into isolated units asthe increasing of Li2S content.
