为便于综合考虑废弃物排放的数量和质量，结合热力学第一定律和第二定律，引入化学（火用）概念，以1978-2004年中国交通运输系统为例，对主要气体污染物NO、SO2、CO和主要温室气体CO2和CH 4进行了分析。在对化学（火用）排放因子进行具体估算的基础上，详细计算了整个交通运输系统及其公路、铁路、水路和民航4种运输方式的总排放量和（火用）排放强度，并与传统的质量度量方法进行了比较，为环境政策的制定提供了重要的依据。(C)2009 Elsevier B. V.保留所有权利。
To facilitate the aggregation of both quantity and quality of waste emissions, the concept of chemical exergy combining the first and second laws of thermodynamics is introduced for a unified account of gas pollutants and greenhouse gases, by a case study for the Chinese transportation system 1978-2004 with main gas pollutants of NO, SO2, CO and main greenhouse gases of CO2 and CH4. With chemical exergy emission factors concretely estimated, the total emission as well as emission intensity by exergy of the overall transportation system and of its four modes of highways, railways, waterways and civil aviation are accounted in full detail and compared with those by the conventionally prevailing metrics of mass, with essential implications for environmental policy making.
