摘要: Ｘ射线荧光分析用的Ｌｉ２Ｂ４Ｏ７玻璃熔片经长期放置后，Ｍｇ，Ｓｉ和Ａｌ等元素的Ｘ射线强度发生了很大变化，尤其是Ｍｇ的强度增大很多，以至无法进行准确分析，对于长期放置的熔片，可以用重新熔融的方法进行处理。Abstract: he X-ray intensities of Mg,Si and Al show changes in a long time storage of the Li_2B_4O_7glass disks.The increase of the Mg intensity is so great that the analysis is no longer accurate.However,the difficulty can be overcome by a refusion of the glass di
