摘　　要：设计了一种可用于分析化学实验及企事业单位化验室的复合式滴定台,方便了相关人员的实验操作,并大大提高了实验台利用率;发明了一套可修复损坏的酸碱式滴定管的仪器;探索了一种解决酸碱式滴定管刻度线读数模糊不清问题的方法,方便了学生读数。通过以上改进,节省了教学成本。A new- type burette holder was designed for analytical chemistry experiments and testing laboratories of enterprises and institutions. An instrument for repairing the damaged burettes was also invented. In addition, the unclear scale lines of burettes can be easy to read by the new method. Thus, the teaching cost was saved and the students would fell easy in a titration experiment.
