摘要
通过对NMHC与TVOC的定义及现有分析方法进行比较,创造条件对NMHC与TVOC的数值进行比较,详细分析了NMHC与TVOC的关系及同等条件下对NMHC与TVOC的数值差异进行分析,揭示了同等条件下NMHC的监测数据大于TVOC的监测数据的主要原因在于两者计算时选择的参比物不同。
This paper explains the relation between non-methane hydrocarbon s(NMHC)and total volatile Organic compounds(TVOCs)by their definitions and analytical methods.In the creation of the same conditions,the numerical difference between NMHC and TVOCs is analyzed in detail.It is revealed that the main reason that NMHC monitoring data is larger than TVOC monitoring data lies in the different reference compounds used in the calculations.
