摘　　要：目前,时间温度指示器匹配方法多依赖于参数耦合、相关性分析、实际物流过程的调试验证等方法,鲜有从匹配机理出发,在反应进度上剖析时间温度指示器的匹配要求和规律。本文在多级反应动力学模型的基础上,以保持时间温度指示器与待测农产品的反应进度一致性作为目标,建立了时间温度指示器匹配的理论和方法,并通过理论推导和实证模型验证了时间温度指示器与待测农产品之间匹配的条件。当指示器与待测农产品服从任意多级反应动力学模型的匹配条件(二者在任意合理的恒温条件下的有效反应时间相等或二者等量线重合)时,即可使用该指示器预测对应农产品的品质变化和货架期,此时二者的反应速率函数存在一定比例关系。借助该方法推导出可以精准指示科瑞森无核葡萄硬度的不同级反应动力学方程,证明了该方法的可行性。The matching method for time temperature indicator(TTI)is the critical factor affecting the application of intelligent indicator.Most current methods depend mainly on the corresponding parameters coupling,correlation analysis and practice logistics verifying without concerning about the reaction extent in matching mechanisms between TTI and agri-produce which needs to be monitored.The relationship between remain shelf life and reaction extent was established and a new matching method between TTI and agri-produce was constructed through keeping the consistency of their reaction extents based on the n-order kinetic models.After a series of analysis and formula,the condition for matching between them was the valid reaction time or remain shelf life of them under any reasonable isothermal process were equal,or the contour lines of them were coincident,no matter whether the orders of their kinetic models were equal or not.In this case,there was a proportional relationship between the reaction speeds of them which was a key character under matching condition.By using the result above,three kinetic models with different orders were constructed,and the matching method was verified based on the consistency of their reaction extents,the appreciate kinetic functions of TTIs for indicating the firmness quality of Crimson seedless grape precisely under alternative and constant temperature logistic was deduced in different order kinetic models.The conclusions validated the feasibility and effectiveness of the proposed method,which could promote the application of TTIs.
