| 摘 要： | 用α－Fｅ２Ｏ３等复合金属氧化物为材料制成一氧化碳敏感元件．其特点是：在CＯ的低浓度范围（50ppm附近）．取样电阻为１kΩ 时，灵敏度为１１．８mV／ppm；响应时间小于５s，恢复时间小于20ｓ．功耗小于0．3W．作者认为其气敏机理应是表面控制型．

| Abstract: | A CO gas sensor based on composite metal oxides(-FeO) has been prepared. It has the following characterstics: a secsitivity of 11.8mV / ppm near a concentration of 50ppm with a series resistance of 1K, a response time smaller than 5s, a recovering time less than 20s, and a power consumption less than 0.3W. The mechanism has been recognized to be a surface-control type. |
