摘　　要：对2013年哈尔滨市不同供油方式的柴油车排气细颗粒物或黑碳测量参数—光吸收系数进行了统计分析,结果表明:涡轮增压和自然吸气供油方式光吸收系数均值分别为1.39 m-1和1.27 m-1,超标率分别为5.8%和2.4%,采用颗粒物控制措施及排气装置强制维护降低了颗粒物排放,符合排放标准。We analysed light absorption coefficient - measurement parameter of fine particles or black carbon from exhaust of diesel vehicles with different oil supply mode in Harbin city in 2013. The results indicated that average values of light absorption coefficient of turbocharged engine and naturally aspirated engine were 1.39 m^-1 and 1.27 m^-1 respectively. The ratios that exceed the emission standards were 5.8% and 2.4% respectively. The implementation of particulate control measures and the exhaust forcible maintenance reduced the exhaust particulate matter emissions to meet current standards.
