摘　　要：近来接连发生的重大致病性微生物对人类社会的危害事件,使人们对疾病控制和预防的重视提到了前所未有的高度,公众对自身居住、工作和生活环境的卫生要求越来越高。The small samples of China fir （Cunninghamia lanceolata） /TiO2 composite were made by sol-gel method and MWLPD （microwave assistant liquid phase deposition） method for the first time （XRD result shows the size of crystal TiO2 are 16.4 and 28.3 nm respectively）.It has been verified by antibacterial testing that the antibacterial rates of samples reach up to above 90% .Escherichia coli,Salmonella typhimurium,Staphylococcus aureus and Bacillus subtilis were regarded as testing target in the antibacterial testing.The antibacterial function of samples is long lasting and broad spectrum.The testing result shows that the antibacterial effect is influenced by light supply and testing temperature.Introducing the TiO2 nanotechnology as photocatalysis antibacterial agent into wood industry will promote wood modification and development of multi-function wood product.
