摘　　要：对不同x值的La_(1-x)Sr_xFeO_3纳米微晶材料的基本性质,尤其是气敏特性进行了比较详细的研究.结果表明La_(0.6)Sr_(0.4)FeO_3和La_(0.4)Sr_(0.6)Fe0_3材料对乙醇气具有相当高的灵敏度、良好的选择性及响应恢复特性.Some characteristics of nanocrystalline La1-xSrxFeO3──based materials with differ-ent x values, especially. It's gas-sensing properties have been studied. Results showLa0. 6Sr0. 4FeO3 and La0. 4Sr0. 6FeO3──based material with very high sensitivity and good selectivi-ty and response recovery propertiesto C2H5OH.
