摘要
Based on an improved effective-medium theory and a proper treatment of ac response of grain boundary barrier layer, the theoretical relationships describing ac electrical properties of heteroge-neous electroceramics are discussed in terms of the theoretical relation-ships, and some important results consistent -with experimental results are obtained.
