摘　　要：对不同退火工艺下制得的化学法氧化锌电阻片的微观结构及脉冲电流性能作了对比分析 ,得出了脉冲电流冲击性能与退火温度和时间的关系。Comparison has been made between annealing processes in chemical processing of ZnO surge varistor in respect of surge current performance and correlation between surge current performance and annealing temperature and duration is established, which may serve as a practical basis for determination of annealing process in batch chemical processing of ZnO varistors.
