摘　　要：本文研究了在彩电消磁用PTCR热敏电阻分别烧渗Ag-Zn电极和Al电极,研究了两种电极对PTCR元件常温断续负荷的影响,分析了失效机理,根据结果我们选取合适的电极作为实际生产中的电极。Fritted-Al electrode and fritted-Ag-Zn electrode in degaussing PTCR for color TV set were prepared . The influence of these different electrodes on the current shocking of PTCR was investigated. The cause of failure was analyzed, from which we could choose the better electrode as the one for practical production.
