“家用煤气灶”标准(CJ4-83)对燃烧废气中一氧化碳含量的测试方法、指标要求,已有明确规定。 烟气测定的结果不仅与一氧化碳测试过程有关,而且与取样过程有关。标准中已规定了取样方法,这方面已有人作过专门研究。本文只讨论按标准测量一氧化碳时的方法误差和减少误差的措施。 为了消除取样过程中混入空气量的影响 “Household gas stoves” standard (CJ4-83) on the combustion exhaust gas carbon monoxide test methods, indicators, has been clearly defined. The result of the flue gas determination is not only related to the carbon monoxide test process, but also to the sampling process. Sampling methods have been provided in the standard, and special studies have been conducted in this area. This article only discusses methods of measuring carbon monoxide by standard error and measures to reduce errors. In order to eliminate the impact of mixed air volume in the sampling process
