摘　　要：采用一台高灵敏的生物活体单光计数系统对淡水鱼的主要超微弱发光特性进行了研究.淡水鱼的各种不同脏器的光子辐射强度数值为3.6—97.3CPS.发射光谱的最大值接近640nm处和460nm附近.实验结果表明,超微弱光子辐射的总强度随所测的时间而变化,加入UOUO_2^(++)离子之后,其发光强度下降.The major properties of ultraweak photon emission from freshwater fish have teen studied by a highly sensitive single-photon counting system for living object. Intensity of photon emission from various organs of freshwater fish amounts to 3.6 to 97.3 cps. The spectrum is characterized by a maximum near 640 nm and an increasse in near 400 nm. Experimental results showed that the total intensity of ultraweak photon emission varies within time measured and it is decreased after adding UO2++ ions.
