摘　　要：根据大气中碳黑气溶胶在可见光及近红外波段具有较强的吸光特性,研制了可检测碳黑气溶胶的专用仪器。本文介绍了该仪器的检测原理、硬件系统设计和软件系统设计。仪器采用单片机控制信号的采集、处理和显示,能实时快捷地检测大气中碳黑气溶胶的浓度。对比实验表明,该仪器设计合理,可满足碳黑气溶胶在线检测的要求。An instrument based on the principle of optical attenuation was developed for the real-time measurement of black carbon aerosol in atmosphere. The working principle, hardware design and software design of the instrument are introduced. A single chip processor is used to control the collecting, processing and displaying of signals. The instrument can detect the concentration of black carbon aerosol in atmosphere rapidly. Comparative experiments show that the design of the instrument is reasonable and the instrument is able to meet the requirement of on-line measurement.
