The scaling of respiratory metabolism with body size in animals is considered by many to be a fundamental law of nature. One apparent consequence of this law is the scaling of physiologic time with body size, implying that physiologic time is separate and distinct from clock time. Physiologic time is manifest in allometry relations for lifespans, cardiac cycles, blood volume circulation, respiratory cycle, along with a number of other physiologic phenomena. Herein we present a theory of physiologic time that explains the allometry relation between time and total body mass averages as entailed by the hypothesis that the fluctuations in the total body mass are described by a scaling probability density.
许多人认为，动物的呼吸代谢与体型的比例关系是自然界的基本规律。这一规律的一个明显结果是，生理时间与体型的比例关系，这意味着生理时间与时钟时间是分开的、不同的。生理时间表现在寿命、心动周期、血容量循环、呼吸周期等多种生理现象的异速生长关系中。本文提出了一种生理时间理论，该理论解释了时间与总体质量平均值之间的异速生长关系，其假设是，总质量的波动可以用一种比例概率密度来描述。
