本文综述了近年来对鸡胚温度调节能力的研究进展，讨论了鸡胚突然冷却和冷却准平衡状态的基本认识，以及鸡胚的热传导和产热特性，并设计了两种冷却试验，以降低冷却过程中的热损失率，研究了早熟和成熟胚胎对冷却的微弱补偿代谢反应，本文报道了鸡胚瞬时心率（IHR）对降温的反应。《国际卫生条例》的基线上升并出现振荡。HR振荡可能是一种与体温调节有关的现象，需要研究。
We reviewed our ontogenetic studies of thermoregulatory capacity in avian embryos in relation to metabolic responses to egg cooling.Basic understanding of abrupt egg cooling and quasi-equilibrium state of cooling was discussed together with egg's thermal conductance and heat production.Two cooling tests, which were designed to minimize the rate of heat loss during cooling, were conducted to investigate a feeble compensatory metabolic response to cooling in precocial and altricial embryos, and models for early development of homeothermy in birds were suggested.Instantaneous heart rate (IHR) response to cooling was measured in chick embryos. The baseline of IHR rised and became oscillating. HR oscillation may be a phenomenon related to thermoregulation, which needs to be studied.
