The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.
聚氧活化曝气增氧机采用磁性工程技术,将空气中的氧经聚氧器聚集活化后送到水下主机的混合室,由水下的磁化器和活化富氧空气快捷完成水气合成程序,在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡,这些随射流、射向水下方的小气泡,其动能消耗至零后,在水中的浮力作用下、开始缓慢上升,由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升,这些小气泡在短时间很难浮上水面,因此延长了小气泡在水中的停留时间和行走路程,大大提高水中溶解氧的效率,使该机的动力效率明显高于传统曝气装置。

A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.

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.
