摘　　要：根据GB/T 28209—2023《硼硅酸盐玻璃化学分析方法》测量硼硅酸盐玻璃中三氧化二硼的含量,通过建立数学模型分析检测过程中不确定度的来源,对测量结果进行不确定度评定,通过计算可知,对滴定终点的判断是影响测量结果的最主要因素。According to GB/T 28209—2023 Methods for Chemical Analysis of Borosilicate Glasses,the content of boron trioxide in borosilicate glass was measured.Based on this detection method,a mathematical model was established and the sources of uncertainty in the detection process were analyzed and evaluated.According to the results,it can be seen that the judgment of the titration endpoint is the biggest factor affecting the determination.
