Based on the traditional metal specific heat capacity measurement method, after various researches, two improved measurement methods have been obtained: Hybrid method, which measures metal specific heat capacity using high-temperature points for water with mixed measurement; Comparison method, which measures the metal specific heat capacity in accordance with Newton's law of cooling. Both measurement methods have high precision and are also easy to operate.
