摘　　要：对一种新型光致变色时间-温度指示卡(TTI)系统应用性进行了研究,结果表明,根据Arrhenius模型计算出在不同的紫外光照射时间的激活能在23.2-25.3kcal.mol-1之间,通过建立质量特性图可计算不同产品的适宜激活时间,从而确定产品的货架期,说明该新型TTI系统可用于多种食品从生产到消费的冷链贮运的可贮型监测。A detailed investigation of the behaviour of a new printable photochromic time-temperature indicator （333） was conducted. The reproducibility of the charging process and the disco｜ouration process of the TTI were analysed. For different charging times the calculated activation energies based on the Arrhenius model ranged from 23.2 to 25.3kcal.mol depending on the UV light irradiation （charging time）. A quality contour diagram was estab- lished to define the appropriate charging time for different kinds of products. Due to the possibility of defining the shelf life of a TrI by different charging times, this novel TFI constitutes a reliable tool to monitor the cold chains of a broad range of food products on their way from production to consumption.
