摘　　要：制备了在相对湿度为 2 0 % RH～ 98% RH范围内电阻值变化 3个～ 4个数量级的(Ba,Pb) Ti O3 陶瓷湿敏电阻 ,应用固体物理的无序系统理论解释了 (Ba,Pb) Ti O3 陶瓷的晶粒半导化 ,从表面电导及表面势垒的观点出发 ,分析其吸湿特性 。In this paper the humidity sensible (Ba,Pb)TiO 3 ceramics resistance has been prepared, with its resistance value varying 3~4 numerical rates in the scope of 20%RH^98%RH 0f relative humidity. It also ecplained the crystal semi conduction of the (Ba,Pb)TiO 3 ceramics with the unordered system theory of the solid physics. From the surface conduction and surface potential barrier, the author analyzed and explained the humidity sensible features of (Ba,Pb)TiO 3 ceramics.
