RT Journal Article SR Electronic T1 Thermal Radiation in Metabolic Chambers JF Science JO Science FD American Association for the Advancement of Science SP 115 OP 117 DO 10.1126/science.166.3901.115 VO 166 IS 3901 A1 Porter, Warren P. YR 1969 UL http://science.sciencemag.org/content/166/3901/115.abstract AB Emissivities and ratios of surface areas of metabolic chambers and their contents have been usually ignored in studies of the metabolic rates of animals.
