摘　　要：本文对高Tc PTC热敏电阻的电极制作和阻湿特性测试问题进行了讨论,对Tc高达700～800℃热敏电阻拟用金属铂作电极。设计了直接将铂丝压入电阻的模具,并利用计算机测试阻温特性。This paper discusses two problems: making electrode for the high Tc PTC, and measuring the resistivity - temperature characteristics. Metal platinum is used as electrode when Tc is 700~ 800℃. A mould is designed and used to press platinum wire directly into thermistor. In measuring resistivity-temperature characteristics computer is used, so that it is reliable and copable of achieving progress in carrying on the project of “The trial produce of high temperature PTC material”.
