Entropy productions within nude subjects in respiration calorimeters are calculated from the corresponding energetic data obtained by Du Bois et al. (1952, J. Nutr. 48, 257-293.). The entropy production for men is constant at environmental temperatures from 24-34 degrees C. The metabolic entropy production comprises 98.6% of the total entropy production. The entropy production for women shows a minimum at 30 degrees C (the middle of the neutral zone), a small rise in the cold zone and a trend toward a rise in the warm zone; the average entropy production for women is 8.7% smaller than that for men. The entropy production rises from 0-2 years of age, and decreases rapidly from 2-25 years of age and then gradually to 85 years of age. The entropy production does not seem to achieve a minimum or a level in the lives of men and women. Based on these results, a three-stage hypothesis of entropy production in human life is proposed.
呼吸热量计中裸体受试者的熵产生量是根据杜波依斯等人（1952年，《营养学杂志》48卷，257 - 293页）获得的相应能量数据计算得出的。男性的熵产生量在24至34摄氏度的环境温度下保持恒定。代谢熵产生量占总熵产生量的98.6%。女性的熵产生量在30摄氏度（中性区中间）时达到最小值，在寒冷区域略有上升，在温暖区域有上升趋势；女性的平均熵产生量比男性小8.7%。熵产生量在0至2岁时上升，在2至25岁时迅速下降，然后逐渐下降至85岁。男性和女性一生中的熵产生量似乎都未达到最小值或稳定水平。基于这些结果，提出了人类生命中熵产生的三阶段假说。
