查询词典 oh

Compared with HA in water-contained organic solvents, the pigment in micelle had higher pKa value and higher fluorescence quantum yield. Moreover, the quantum yield of active species produced from photosensitization, 1O2 and ·OH, increased as well. As a result, the photosensitivity of HA was enhanced.

相对于含水有机体系，HA在胶束中基态的 pKa值升高，荧光量子产率增大，光敏反应产生的活性中间体1O2 和·OH的产额增加，从而提高了其光敏活性，这在光敏损伤作用中具有重要的生物学意义。

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.
