| 摘要:利用便携式排放测试系统（portable emission measurement system，PEMS）对一艘小型集装箱船舶开展在实际航行工况下的排放试验，研究该船舶主机不同工况下的排放因子、NOx和颗粒物瞬态排放特性和颗粒物粒径分布。结果表明：CO、THC（总碳氢）、NOx、PN（颗粒物个数）在离港和进港工况下基于燃油的排放因子均高于巡航工况；各排放物在离港工况下基于距离的排放因子均高于其他工况；在巡航工况下NOx瞬时排放率显著高于离港和进港工况；离港和进港工况下的核态颗粒数显著高于巡航工况，分别占各工况总颗粒数的68.94%和81.56%；巡航工况下的聚集态颗粒数显著高于离港和进港工况，占巡航工况总颗粒数的74.43%；试验全程核态颗粒占总排放颗粒数的61.89%。 |

| Abstract:Emission test of a small container ship was conducted based on the portable emission measurement system（PEMS）to study the emission factor，transient emission characteristics and size distribution of particles.The results show that：emission factor of CO，total hydrocarbons（THC），NOx and particle number（PN）based on fuel is higher on port departure and arrival modes than on cruise mode；emission factor of all emissions based on distance is higher on port departure mode than on other modes；instantaneous emission rate of NOx is higher on cruise mode than on port departure and arrival modes；number of nucleation mode particle is higher on port departure and arrival mode than on cruise mode，accounting for 68.94% and 81.56% of the total particle number on each mode，respectively；the number of accumulation mode particle is higher on cruise mode than on port departure and arrival modes，accounting for 74.43% of the total particle number on cruise mode；through the whole test process，nucleation mode particle accounts for 61.89% of the total particle number. |
