采用高压和低压汞灯紫外射线辐照制备了Cu2O超细粉经过校正的低压汞灯单色254nm辐照的宏观反应动力学近似为一级反应与60Co源γ射线辐照和200MeV直线加速器电子束韧致辐射转换而来的高能γ射线辐照相应溶液的宏观动力学做了比较．结果表明，三者有一定的相似性紫外射线辐照生成Cu2O超细粉的过程包含有光化学效应和辐照效应，有水合电子的作用.
The macroscopic reaction kinetics of monochromatic 254nm irradiation of low-pressure mercury vapor lamp with Cu2O ultrafine powder prepared by high-pressure and low-pressure mercury lamp UV irradiation was approximately the first order reaction with 60Co γ-ray irradiation and 200MeV linear accelerator electron beam Compared with the macroscopic kinetics of the corresponding solutions of high energy gamma rays converted from bremsstrahlung radiation. The results show that there is a certain similarity between the three. The process of ultra-fine powder of Cu2O generated by UV irradiation includes photochemical effect and irradiation effect, and has the function of hydration electron.
