结果 不同浓度的食醋溶液作用不同时间对金黄色葡萄球菌、大肠杆菌和白色念珠菌的杀灭效果不同，浓度越大、作用时间越长杀菌效果越好（F=6.89～156.83，P.05）；对手自然菌作用2 min，平均杀灭率为0.991 5±0.003 2；对厨房内台面、砧板、菜刀、碗柜、瓷碗、冰箱保鲜室表面擦拭消毒10 min，对自然菌的平均杀灭率在0.972 0以上；对室内空气自然菌的杀灭率随熏蒸时间的延长而提高（F=121 2.13、502 4.46，P.05），当室内有人时，杀灭率有所降低（t=5.08～30.48，P.05）；置于54 ℃恒温箱（相对湿度≥0.75）存放14 d，醋酸总含量下降

In the end, the synthesis condition and influential factors of PU-titania (TiO2) process, such as manufacturing sol (including the amount of water, the amount of PU/Titanium butyrate, the concentration of the solution, the pH value, the kind of alcohol), aging process, theoretical analysis of the dipping process, dry and heat treatment of the gelation, were also discussed especially. FT-IR、SEM、TEM、DLS techniques were applied to analyze and study the reaction mechanism and watch the surface and section of the PU-TiO2 membrane. According to above, it was inferred that PU-TiO2 membrane (containing K600) was better composite.
