| 摘 要： | 监测中子积分通量是裂变径迹技术的重要组成部分。铀玻璃监测中子积分通量是国际裂变径迹定年标准化工作组推荐的重要方法之一，铀玻璃测定法还普遍用于测定样品中的铀含量及其空间分布。本文介绍的铀标准玻璃，经过多家实验室定值测定，表明其稳定性、均匀性均达到国家一级标准物质的要求，抗酸性能达到Ⅰ级光学玻璃水平，抗潮性能达到Ⅱ级光学玻璃水平。其它性能指标均达到或超过美国国家标准局的同类产品。

| Abstract: | Examing neutron integral flux is an important part of fission track technique, and determining neutron integral flux by using uranium standard glass is recommended as a mainmethod by international Fission Track Standardization Group for age-dating. The uraniumglass determination method is also commonly used to determine the uranium content as wellas the space distribution pattern of uranium samples. The uranium standard glass this paperintroduced acccording to the determined values in various laboratories, shows that its stability and homogeneity can meet the demand for first class National Standard Meterials and itsresistance to acidity reaches the level of first class optical glass, while its resistance to humidity reaches the level of second class optical glass. Other functional indexes of the glassare equal to or surpass those of same products of NBS. |
