冰的熔解热实验装置的改进

Improvement on experiment device of the heat of fusion of ice

将保温杯引入到测定冰熔解热的实验中,提高了实验装置的保温性能;利用马达和风扇自制了搅拌装置,保证了搅拌均匀性;利用单片机、传感器模块和液晶屏实现了温度数显功能,提高了实验精度.通过对比改进前后的实验装置的实验数据可知,改进后的实验装置有效地减小了实验误差.

Three improved measures were designed for the experiment device of the heat of fusion of ice .Firstly ,vacuum cup was used in the experiment to increase the thermal insulation properties . Secondly ,a churn‐dasher was self‐made by using motor and fan to insure the homogeneity .Thirdly , the temperature digital readout function was realized by reasonable assembly of single chip micyoco , sensor and liquid crystal display ,and the experiment precision was raised .By comparing the experi‐ment data of before and after the improvement device ,improved device could effectively reduce the ex‐perimental error .
