在90种禽类中建立了孵化长度(I)、水汽导度(\({{\text{G}}_{{{\text{H}}_{\text{2}}}{\text{O}}}}\))，和总功能孔面积(AP)与蛋重(W)的异速生长关系。导出了一个表示三个变量之间相互关系的常数，即(\({{\text{G}}_{{{\text{H}}_{\text{2}}}{\text{O}}}}\)·i)/W=5.13±0.86S.D.[mg/(g.torr)]。对O2和CO2电导得到了类似的常数，并讨论了孵化过程中鸡蛋的新陈代谢需要和水分损失的关系。研究表明，每克卵的总失水量和总摄氧量与卵大小和孵化时间无关。
Allometric relationships of incubation length (I), water vapor conductance (\({{\text{G}}_{{{\text{H}}_{\text{2}}}{\text{O}}}}\)), and total functional pore area (Ap) as a function of egg weight (W), were established in 90 species of birds. A constant was derived which expresses the interrelationship between three variables.Thus (\({{\text{G}}_{{{\text{H}}_{\text{2}}}{\text{O}}}}\) · I)/W = 5.13 ± 0.86 S.D. [mg/(g·torr)]. Similar constants were derived for O2 and CO2 conductances and discussed in relation to the metabolic requirements and water loss of eggs during incubation. It is proposed that the total quantity of water lost and the total quantity of O2 taken up per gram of egg is independent of egg size and incubation period.
