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。

The gas coming off the potassium chlorate is oxygen. Because of this, it is often used in airplanes, space stations, and submarines as a source for oxygen.

氯酸钾释放出的是氧气，因此常用在飞机、空间站和潜艇中作为氧气源。

Thereafter, some research work about the effect of additive percentage of pH value buffer solution and oxygen concentration in flue gas on this system of flue gas desulfurization with pyrolusite pulp in a single JBR was carried out, and it was illustrated that the optimized additive percentage of pH value buffer was 30% and 10% when oxygen concentration in flue gas is 21% and 7% respectively.
