人的体温一般恒定在37℃左右,这是在体温调节中枢控制下,产热和散热平衡的结果。人体的产热主要是体内氧化的结果,而散热则以传导、对流、辐射、蒸发等方式。通常室温在15~25℃时,人体散热60%靠辐射,25%靠蒸发,12%靠对流,少数为传导。由于外界气温及机体活动情况的不同,散热方式可发生变化。如果气温升高,蒸发散热将
People’s body temperature is generally constant at about 37 ℃, which is under the control of the thermoregulatory center, the result of heat balance and cooling. The body’s heat is mainly the result of oxidation in the body, while the heat is conduction, convection, radiation, evaporation and other means. Usually room temperature at 15 ~ 25 ℃, 60% of human radiation by radiation, 25% by evaporation, 12% by convection, a few for conduction. Due to the outside temperature and the different body activities, cooling methods can change. If the temperature rises, evaporative cooling will be
