摘要翻译:
我们研究了将有机体代谢率$B$与有机体质量$M$联系起来的标度律$B\propto m^{\alpha}$,其中$\alpha$通常被认为是3/4。由于简单的量纲分析表明$\alpha=2/3$,我们认为这是一个可以通过实证研究检验的无效假设。我们重新分析了Heusner、Bennett和Harvey、Bartels、Hemmingsen、Brody和Kleiber汇编的哺乳动物和鸟类的数据集,发现几乎没有证据支持$\alpha=2/3$而支持$\alpha=3/4$。对于哺乳动物来说,我们发现一种可能的对较大质量的比例分解反映在$\alpha$的系统增加中。我们还回顾了基于量纲分析、营养供应网络和四维生物学的$\α=3/4$的理论依据。我们发现,现有的关于$\alpha=3/4$的理论需要的假设使它们无法令人信服地拒绝$\alpha=2/3$的无效假设。

英文摘要:
We examine the scaling law $B \propto M^{\alpha}$ which connects organismal metabolic rate $B$ with organismal mass $M$, where $\alpha$ is commonly held to be 3/4. Since simple dimensional analysis suggests $\alpha=2/3$, we consider this to be a null hypothesis testable by empirical studies. We re-analyze data sets for mammals and birds compiled by Heusner, Bennett and Harvey, Bartels, Hemmingsen, Brody, and Kleiber, and find little evidence for rejecting $\alpha=2/3$ in favor of $\alpha=3/4$. For mammals, we find a possible breakdown in scaling for larger masses reflected in a systematic increase in $\alpha$. We also review theoretical justifications of $\alpha=3/4$ based on dimensional analysis, nutrient-supply networks, and four-dimensional biology. We find that present theories for $\alpha=3/4$ require assumptions that render them unconvincing for rejecting the null hypothesis that $\alpha=2/3$.
