摘要

It is not every day that a 'law of nature' is challenged by empirical data, but on page 457 of this issue we find just that. Peter Reich and colleagues offer convincing evidence that refutes the idea that Kleiber's law — the all-encompassing prediction that metabolic rate should scale as the 3/4 power of size across animals — can be extended to vascular plants (Fig. 1). Their findings question our understanding of how plant metabolism is organized. More broadly, they raise serious doubts about the notion that there exists a unified metabolic theory of scaling based on mechanisms that apply equally across plants and animals.

1. GUIDELINES FOR PILOT PLANT-TESTINGA`1. The minimum volume should be 250 gal (950 L) for scalable mass-transfer testing. A 20-gal tank can be used to evaluate blending and impeller placement 2. Liquid-level-to-tank-height ratio, and tank geometry should be similar to full scale 3. Baffles and heating coils on pilot scale should be similar to full-scale tank 4. Test the fluid with the organism, if possible. If not, use water, knowing the oxygen transfer rate results will be different [J] . Chemical Engineering Group Chemical Engineering . 2014,第3期
