用钴-60γ射线对接种于卵黄液中的大肠杆菌进行辐照灭菌，并测定了卵黄液的抗体效价、活性氧和卵黄液保存期的变化。结果表明：1.大肠杆菌在卵黄液中的D10值为0.31～0.37kGy,杀灭卵黄液中大肠杆菌的照射剂量为3kGy;2.辐照量在15kGy以下时，对卵黄液的抗体效价没有影响或仅有轻微影响；3.经8kGy照射后的卵黄液在常温、4℃、-10℃条件保存时，保存期明显长于未照射的卵黄液。

The E.coli inoculated into yolk was kill ed with 60Co-γ rays.Thechanges of the antibody titres, 0xygen Free Radicals,and the p e riod of storing of the yolk were tested.The results showed:1.D10 value of E.coli in the yolk was 0.31～0.37kGy. 3kGy irradiation dosage wa s needed to kill E.coli in egg yolk;2.The dosage of less than 15kGy of 60 Co-γ rays didn't destroy the antibody in yolk;3.Yolk treated with 8kGy 60Co-γ rays coul d be stored for a longer time than untreated yolk at room temperature,4℃，-10℃.
