| 摘 要： | By analogue experiment of exhaust gas, thesensitive characteristics of titania to air/fuelratio was investigated. The effects of some impuri-ties on the electric conductivity of TiO_2, thedeviation of (A/F)c from (A/F)s in nonequilibriumgas system and the self-catalytic oxidation of TiO_2were explained respectively. The effects of ca-talyst, porosity and thickness of sensor element onthe response time was also analyzed.
