| 摘 要： | 本文阐述了低温生物学、低温医学与热物理的关系；着重讨论生物体低温保存的问题，细胞和组织的低温损伤是溶液冻结相变过程所引起的冰晶损伤和高浓度溶液的损伤；这个过程和传热传质密切相关；而低温保存的机理则是溶液的非晶态化（玻璃化）。本文还讨论了低温生物医学当前的研究热点，以及其中的热物理问题。

| Abstract: | The relation between cryobiology, cryomedicine and thermophysics is discussed. The injury of cells and tissues during freezing is caused both by ice forming, and by the highly concentrated solution; and this process is closely related to heat and mass transfer. The mechanism of successful cryopreservation is the vitrification (non crystallization) of solutions. The recent hot spots of cryobiology and cryomedicine are discussed; the thermophysics problems concerned are analyzed also. |
