摘　　要：针对传统机动车尾气颗粒物检测设备测量精度低、环境适应性差、无法同时测量质量浓度和数量浓度等问题,设计出一种机动车颗粒物快速检测仪。检测仪以电荷法测量原理为基础,可同时测量出23 nm~2.5μm颗粒物的质量浓度和数量浓度。实验结果表明,该检测仪具有稳定性好、测量精度高等优点,可以满足实际道路执法检测的要求。In view of the problems of low measurement accuracy,poor environmental adaptability,and the inability to measure the mass concentration and quantity concentration of particulates in exhaust gas at the same time of traditional motor vehicle exhaust particulate detection instruments,a kind of motor vehicle particulate matter rapid detector was designed.The detector was based on the principle of charge.It can simultaneously measure the mass concentration and quantity concentration of particles between 23 nm and 2.5μm.The measurement results show that the detector has the advantage of good stability,high measurement accuracy,and can meet the requirements of the actual road law enforcement detection.
