| 摘 要： | 尾气遥测作为一种快速监测技术广泛应用于机动车排放监测，然而其动态检测的准确性评价手段有限。通过对比机动车尾气遥测系统的静态的校准方法，发现燃烧方程的辅助计算可以修正测量数据，克服仪器在动态测试中气体扩散的影响。利用燃烧方程分别归纳了以1,3丁二烯与丙烷为碳氢标志物的标准气体的比例关系，并配制和验证了2种标准气体用于机动车尾气遥测系统的动态准确度检测。研究结果表明符合燃烧方程的标准气体能够更好地表征仪器对低浓度组分动态测量结果的准确性。研究结果可为机动车尾气遥测仪检测用标准气体制备提供指导，优化动态准确度的计量检测条件。 |

| Abstract: | Remote sensing of exhaust gas is widely applied in vehicle emission monitoring. However, the evaluation method for dynamic measurement is limited. Two kinds of static calibration device were compared, the results showed that the assistant computation of combustion equation corrected the measuring data and avoided the influence of diffusion of plume. According to molecular weight difference of C3H8 and 1,3-C4H6 in combustion equation, the ratio of each component in standard gas was definite. And two kinds standard gas were prepared and verified by dynamic measurement. The results indicated that the gas components accorded with the combustion equation could evaluate the accuracy of monitoring date for low concentration components. Thus, the results of the researche could guidance the preparation of standard gas for remote sensing equipment, and enrich the testing methods for dynamic measurement. |
