【Abstract】 According to the practical test, the density of heat flow of the floor in an assembly cold store at a given temperature was analyzed. In other to build a mathematical model of heat transfer, the heat transfer conditions to the floor were simplified, and the analytical result was deduced. At last the temperature field of the floor was calculated in numerical method.更多还原
