摘　　要：大气黑碳气溶胶主要有光学分析法、热学分析法以及热光结合分析法。利用苏州南门国控子站的碳分析数据,对三种黑碳浓度测量方法进行对比并分析其差异来源。主要得出以下结论:黑碳仪衰减系数无普适标准,热学分析法使有机碳碳化、元素碳不完全分离,TOT法协议设置存在争议是三种方法存在差异的主要原因。The main methods for measuring black carbon mass concentration were optical absorption technique,thermal technique and thermal-optical technique. Based on the collation of the carbon data at the monitoring site in Nanmen of Suzhou City,the study compared three methods to analyze the differences. The main source differences among the three methods were as follows: the attenuation coefficient of Aethalometer had no universal standard,separation of OC carbonization and EC of the thermal technique was incomplete,and controversial temperature setting of the protocol of TOT was the main reason of the differences among the three methods.
