摘要
引入时域参数的概念使时域方法可推广用于研究非线性效应的微观机理.决定氧化锌变阻器宏观物性的微观原因可分为4种不同的机构.正反向串联的阻挡层决定其漏电电流,陶瓷中晶粒及其间界层决定其非线性导电指数.阻挡层中空间电荷的自由弛豫时间长达200s.
The microscopic mechanism of non-linear effect is studied using timedomain paramete4s.The macroscopic property of ZnO in varistor is determinedby four different components of the microscopic structures.The leakage curre-nt is determined by the two barrier layers connected in series and the non-lin-ear index of conductivity is determined by grains and intergranular layer.Thefree relaxation time of space charges in barrier-layers is as long as 200 s.
