The capacity for heat production, under the influence of the same amount of noradrenaline, in the rat was significantly higher in the evening (20.00 h) than in the morning (07.00 h). Thyroidectomy produces not only a lower level of heat production, but also a complete disappearance of the differences between the morning and the evening experiments.
在等量去甲肾上腺素的影响下，大鼠产热能力在傍晚（20:00）显著高于早晨（07:00）。甲状腺切除不仅会使产热水平降低，还会使早晨和傍晚实验之间的差异完全消失。
