利用多功能无线电采集器在吉林省开展了冬季燃煤民居室内CO、CO2、气温自动观测和室内外对比观测试验，分析CO和CO2浓度的变化特征及其与用火规律、室内温度的关系。结果表明：吉林省冬季燃煤民居普遍存在CO污染，60％的民居出现浓度持续超过125 mg·m-3的高污染；CO浓度的月变化与燃煤量有关，日变化与用火过程、燃烧阶段和燃烧状态有关；在不同季节、不同城市、不同民居、不同室温及不同燃烧过程中，CO在烟气中所占的比例不同；在点火、持续燃烧、压炉子和熄火等不同燃烧阶段及旺火燃烧、急倒烟和慢倒烟等不同燃烧状态下，CO浓度的变化有显著差异。

CO and CO2 concentrations and air temperature in the indoor and outdoor were observed and compared using a multi-function radio collector in 10 coal-burning residences in Jilin province during winter.The characteris-tics of CO and CO2 concentrations and their relationships with the coal-burning route and indoor air temperature were analyzed.The results show that the indoor pollution comes mainly from CO of the coal combustion.The CO pollution in coal-burning residences is prevalent in Jilin province during winter and about 60% residences appear the persistent high pollution with CO concentrations exceeding 125 mg·m-3 among samples in this survey.The monthly change of indoor CO concentration is related with coal consumption,while its diurnal variation is related with the burning method and the process of burning.The CO proportion in the flue gas differs significantly in dif-ferent seasons,cities,residences,temperature and combustion process.The variation characteristics of CO concen-tration also differ significantly in different burning stages such as lighting the fire,normal combustion,or putting the coal over the fire and extinguishing the fire,and in the different burning status such as burning strongly,revers-ing the smoke flowing direction sharply or slowly.
