摘要
指出了现有的测量Ｔ＇ｇ方法中存在的问题，分析了低温显微ＤＳＣ（差示扫描量热法）系统测定Ｔ＇ｇ的原理。
The glass transition temperature of maximally frozen-concentrated solution is very important to the processing and storage of food. The problems in the curmt methods of measuring glass transition are pointed out and the principle of cryoicroscope-DSC system in T'g measurement is analyzet. It is concluded that cryomicroscope-DSC may become a new type of instrument for accurate measurement of the glass transition temperature.
