The Influences on Photocatalyzing Properties of TiO2

An immobilized TiO 2 photocatalyst is choosed to treat phenol dicharge. The authors study the remove efficiencies under different conditions through experiments, such as lamping lights,time that the photocatalyst is lamped,pH of phenol dicharge and so on. It is showed that a satisfactory can be presented in the condition that the photocatalyst is lamped by mercury light and the time that light lamping lasts 5 hours long and pH of phenol dicharge is in 2.0.     

家蚕第三白卵基因座的突变新成员ω-3^c

西南大学家蚕基因库保存的我国家蚕地方品种“三眠白卵”（编号19-340），其卵色为浅褐色白卵，幼虫低度油蚕。成虫复眼为黑色。采用卵色正常型黑卵系统，白卵标志基因ω-2、ω-3等的遗传系统与其进行杂交，对19—340进行了系统的遗传分析，结果表明该浅褐色白卵为家蚕第三白卵（ω-3：10—19．6）基因的等位点突变。将其命名为chinese white egg3，基因符号为ω-3^c。首次从我国家蚕地方种中发现第3白卵基因座自然突变。
