【Abstract】 Based on a digital controlled constant temperature water bath,a temperature sensor and zirconium sand,a new type of experimental device for measuring the ice melting heat was designed. The constant temperature water bath can be used to provide a stable external temperature for the reaction system,thus,the heat exchange between the system and the external environment can be effectively reduced. The digital thermometer is made by using temperature sensor,which can improve the accuracy of reading. Zirconium sand is worked as insulation material,improving insulation effect. By comparing the experimental data before and after the improvement,it can be seen that the improved experimental device effectively reduces the experimental error.更多还原
