热电法测定固体比热容实验装置

摘要

An experimental apparatus for solid massic heat capacity was developed by thermoelectric method. The adi-abatic apparatus contains a thermal energy converter. The measurement of the data is controlled by single chip micyo-co. The temperature, thermal power and time are automatic recorded. This can dismiss the error of manual work and make the measurement more reliable and repeatable. This apparatus can not only detect the massic heat capacity of the solid but also measure the heat transform rate, the heat conversion coefficient, etc.%研制了一种用热电法测定固体比热容的实验装置.该装置以单片机为主控器,利用帕尔帖片使样品成为孤立系统,自动记录温差电动势、样品温度和时间,消除了人工记录的误差,增加实验的准确性,测得结果的重复性好.除了能测量固体比热容,还可用于测量热交换率、热转换效率等参数.
