摘　　要：介绍了玻璃量器滴定管的用途、分类和容量示值误差的检定,分析和探讨了容量示值误差和流液口最后一滴水珠示值的大小对分析结果的影响。容量示值误差的大小能够影响分析结果的准确性,使被测样品的含量偏离其真实结果,选择合格、合适的滴定管,可以减少分析过程带来的误差,提高分析结果的准确度。The use, classification and verification of indicator error of burette capacity of graduated glass ware were discussed. The influence of indicator error and the last drop of solution on analysis results were analyzed and discussed on benefit of reducing the error in analysis process, and increasing the accuracy of analytical results. The indicator error of burette capacity influences the accuracy of analytical results. The suitable qualified burettes can decrease the error in analysis procedure and increase the accuracy of analysis results.
