Abstract :
The inner metabolizing status can be measured by surface temperature changes of human. These changes involve lots of heat influence in which metabolic heat-production is the most important. Based on processing the data acquired by improved cold stimulation experiment with independent component analysis (ICA), this paper obtains two of main heat component - heat transfer quantity of blood perfusion and heat-production quantity of metabolism. The physiological meaning of these two components is discussed
