摘　　要：混合法测量固体比热容实验一般采用蒸汽加热器对被测金属块进行加热,但用它测得的金属块的温度不准确,从而导致比热容不准确。采取水浴法来加热被测金属块,能够得到一个热平衡态的温度值,从而获得准确的比热容。The mixing method to measure solid specific heat capacity generally uses steam heater to heat the measured metal block. But the measuring temperature of metal block is not accurate, so a new method, the water bath method, is used to heat the metal block, which can get a temperature value of the thermal equilibrium.
