| 摘 要： | 汽车尾气中的有害物主要有CO,HC,NOx,SOx以及一些微粒物质,给人类赖以生存的大气环境带来了严重的危害。汽车尾气用NOx传感器开发主要是为了解决NOx(包括NO,NO2)的排放问题,能够实现准确、快速地测定NOx含量,从而满足大气质量检测和环境保护的要求。目前,NOx气体传感器主要有半导体型、电位型和电流型。主要介绍了这3种汽车用NOx传感器的原理、结构及应用,并简要分析了其向微型化、集成化和智能化等方向发展的趋势。

| Abstract: | The pollutants in automobile exhaust gases mainly are CO,HC,NO_x,SO_x and some particulates.The exhaust gases seriously pollute our living environment.NO_x sensor for monitoring car exhaust gases is studied for monitoring the content of NO_x exhausts gases from automobiles in order to satisfy the requirements of monitoring atmosphere and protecting environment.NO_x sensors can be divided into three types:semiconductor,potentiometric and amperometric gas sensor.Working mechanism,construction and application of the three kinds of sensors are introducted.Development trend of miniaturization,multifunction and integration and intelligence of the automotive sensor is also predicted. |
