从La1-xSrxMnO3材料的结构特征探讨材料的导电机理，认为在1000℃以下材料的导电属于小极化子导电机理，在1000℃以上则转化为非小极化子导电机理．并利用材料电导率与温度关系的试验曲线对小极化子导电机理进行验证．The conducting mechanism of the cathode material La1-xSrxMnO3 was investigated from is structural characteristics. The conducting mechanism which was confirmed by the correlation of conductivity and temperature is the small polaron hopping process at temperatures below 1000℃.
