| 摘要: |
| 对同一场景中同一机动车排放黑烟的行为，采用光电测烟望远镜和黑烟车电子抓拍系统2种方法测定林格曼黑度，以光电测烟望远镜作基准，对黑烟车电子抓拍系统的测量结果进行修正。结果表明，黑烟车电子抓拍系统的测量结果经修正后与光电测烟望远镜的测试结果的相关性系数约为0.977，误差平均值为-0.015，方差为0.032，说明2种测量方法具有良好的相关性和可比性，利用光电测烟望远镜可以为黑烟车电子抓拍系统搭建量值溯源链。 |

| Abstract: |
| Photoelectric smoke detector and electronic snapshot system for black smoke truck were both used to measure the Ringelman blackness of the same truck at the same time. And then, based on the results of photoelectric smoke detector, the measurement results of electronic snapshot system for black smoke truck were corrected. The result shows that the correlation coefficient between the measurement results of electronic snapshot system for black smoke truck and those of photoelectric smoke detector is about 0.977, the average error is -0.015 and the variance is 0.032 after correction. It means the two measurement methods show good correlation and comparability with each other. The photoelectric smoke detector can be used to build the traceability chain for the electronic snapshot system for black smoke truck. |
