| 摘 要： | 基于热光反射法（IMPROVE A）和热光透射法（RT-Quartz）二种协议分析方法和新型OC/EC分析方法对济南市碳质气溶胶含量进行了对比观测.结果表明,协议方法在OC/EC的观测过程中因分析定义会造成碳质气溶胶质量浓度高估或者低估,且膜采样系统使离线分析的OC约为在线的1.65倍,而新型OC/EC测量方法相对于2种协议方法,去除了原理上和环境参数（如VOCs）可能导致的误差,在OC/EC/TC测量结果上均有一定优势,在实际运行中更具有准确性、稳定性和实用性,更加适合颗粒物中OC/EC长期业务化在线测量.

| Abstract: | Based on two protocol analysis methods, Thermo-light reflection method (IMPROVE A) and Thermo-optical transmission method (RT-Quartz), and the new OC/EC analysis method, comparative analysis of carbonaceous aerosol content in Jinan was held in this study. The results show that the protocol methods may lead to overestimation or underestimation of the carbonaceous aerosol mass concentration due to the analysis definition during OC/EC observation process, furthermore, the membrane sampling system made the offline OC about 1.65times online. Compared with the two protocol methods, the new OC/EC measurement method does eliminate the errors that may be caused by principle and environmental parameters (such as VOCs), and has certain advantages in the measurement of OC/EC/TC. With more accuracy, stability and practicality in practical operation, the new method will be more suitable for long-term commercial online measurement of OC/EC in particles. |
