Abstract
The measurement of specific heat capacity is one of the basic measurements in physics,the author determined metal specific heat capacity.Based on Matlab software,one fits the relationship function between time and temperature,and gets its derivation.One also obtains the cooling velocity as a function of temperature by the corresponding relationship between temperature and time.According to the cooling velocity of standard sample and the examining sample at the same temperature,one can get the specific heat capacity of the sample.Compared with the recognized value,the percent error is 0.78.关键词
