摘　　要：为了探索生物超弱光子辐射在禽蛋新鲜度评价和检测方面的应用,研究了25℃和40℃储存温度下鸡蛋超弱光子辐射中自发发光和延迟发光的基本规律。结果表明,在25℃的储存温度下,随着储存时间的延长鸡蛋的自发发光缓慢增长,延迟发光初始光强缓慢降低;在40℃高温下自发发光迅速增长,而延迟发光初始光强迅速下降,鸡蛋的延迟发光服从双曲线弛豫。由延迟发光积分强度和单位时间内的自发发光构建鸡蛋的状态参量,研究发现,在25℃和40℃储存温度下鸡蛋状态参量的变化与哈夫单位的变化呈现良好的线性关系,表明鸡蛋状态参量可以作为鸡蛋新鲜度评价的定量指标。In order to explore application of the ultra weak photon emission in evaluation and detection of eggs freshness,the spontaneous luminescence （SL） and the delayed luminescence （DL） of ultra weak photon emission in eggs at the storage temperature of 25℃ and 40℃ were studied respectively.The results showed that the intensity of SL slowly increased and the initial intensity of DL slowly decreased with storage time at the storage temperature of 25℃.In reverse,the intensity of SL rapidly increased and the initial intensity of DL rapidly decreased with storage time at the storage temperature of 40℃.The DL of eggs obeyed the law of hyperbolic relaxation.The state parameters of egg based on the integral intensity of DL and the SL intensity in unit time were defined in the paper.There was a good linear relationship between the state parameters of egg and Haugh unit at the storage temperature of 25℃ and 40℃.It showed that the state parameters of egg could be a quantitative criterion for assessing the freshness of eggs.
