摘　　要：物质溶解及酸碱中和反应伴随的温度变化具有重要的教学价值,但是中学教材中这两个实验对应的装置却存在操作繁琐、无法同时进行多组实验、数据可视化程度低、教学效果差等问题。基于对教材及文献的梳理,设计了一套融入手持技术的初中化学溶解热及中和热实验的实验装置,旨在提高教学质量,培养学生的创新意识。The temperature changes associated with the dissolution of substances and acid-base neutralization reactions have important teaching value.However,the devices corresponding to these two experiments in middle school textbooks have problems such as cumbersome operation,inability to conduct multiple sets of experiments at the same time,low data visualization,and poor teaching effect.Based on the combing of textbooks and literature,this paper designs a set of experimental devices for chemical dissolution heat and neutralization heat experiments in junior high school with handheld technology,Intended to improve teaching quality and cultivate students innovative awareness.
