利用差示扫描量热仪（DSC）研究了羟基磷灰石（HA）纳米微粒对丙三醇溶液冻结过程中水合性质及玻璃化性质的影响．实验结果表明在中高浓度HA纳米颗粒对溶液水合性质影响显著．与未加纳米颗粒的溶液相比，溶液结晶量减少，未冻水含量增大．在较低浓度溶液中，加入纳米颗粒后玻璃化温度变化不明显，但反玻璃化温度明显升高；当溶液浓度达到60％，加入纳米颗粒后玻璃化温度才有明显的升高趋势，并且玻璃化温度与熔融温度的间距缩短幅度很大．种种结果表明纳米颗粒对实现低温保护剂溶液玻璃化是有利的．
In order to investigate the effects of nanoparticles（HA） on the vitrification properties of cryprotectant solutions at cryogenic temperatures, the hydration properties, vitrification and devitrification of Glycerol aqueous solutions with different sizes and concentrations of HA nanoparticles were employed by differential scanning calorimeter （DSC）. Experimental results indicate that the hydration behaviors can be significantly affected by nanoparticles. Compared with other solutions without nanoparticles the crystallization quantity reduce, unfrozen water increase. At low concentrations glass transition temperature change smoothly after adding nanoparticles, but devitrification tem- perature evidently rise. When concentrations arrive to 60 %, vitrification temperatures rise significantly and the distance between vitrification temperature and melting temperature reduced largely. All of them show that nanoparticles is benefit for realizing virification of cryoproteetant solutions.
