The result showed , the two dimensional image accumulated by photon emission at some hours. The spontaneous luminescence could be measured by means of photon counting and imaging acquisition. The luminescence intensity of root and leaf was different at the same plane image. It showed that PIAS could objectively display the spontaneous ultraweak photon, and this results provided experimental basis for resea...

结果表明，自发光子长时间积累可形成二维图象；光子计数和采集图象均可得到植物体的自发发光；通过实验探测到幼苗的根、叶在同一平面图象有不同的发光表现；光子成像系统可客观地比较生物自发超弱发光，为进一步研究超弱发光机理提供实验基础。

In this paper the thymus DNA of calf and the pBs plasmid are the main objects of our studies in ultraweak luminescence. By means of PIAS(Photon-counting image acquisition), ultraweak luminescence detector and Lambda Bio 40 of UV/VIS spectrophotometer, we studied the UL of DNA induced by the three oxygen free radicals: singlet oxygen Oa, hydroxy radical and superoxide anion(O2 ). We found that the OH can greatly increase the UL intensity of DNA.

本论文以小牛胸腺DNA和质粒pBs为实验材料，利用光子图像探测系统(Photon-counting image acquistion，PIAS)、微弱发光测量仪和UV／VIS分光光度计和生物统计学的成组比较法原理对单线态氧(~1O_2)、羟自由基、超氧阴离子(O_2~-)三种氧自由基诱导DNA超弱发光的变化过程进行了研究，结果发现这三种氧自由基中·OH能诱导DNA的超弱发光发生显著的增强变化，而其他两种氧自由基对DNA的超弱发光并无显著诱导作用。
