| 摘 要： | 本文应用变温11B核磁共振技术研究了RNa2O·B2O3玻璃体系在室温和300℃时硼原子的配位情况。结果表明,当R>0.5时,四配位硼原子数随温度的上升而减少。因此,玻璃态结构也可能随温度变化而改变。

| Abstract: | Temperature-dependent 11B NMR technics have been employed to determine the boron coordination in sodium borate glasses at room temperature and 300℃.The results show that, as R>0.5, the fraction of borons in 4-coordinated will decrease as temperature increases. These resuhs mean that it is possible for glass structure changes as temperature is below the transitional temperature. |

| Keywords: | Temperature-dependent NMR Vitreous Transitional temperature. |
