摘　　要：为了研究卷烟焦油测试过程中的各变异源的差异,采用完全嵌套方差分析和嵌套析因设计分析对各变异源进行分析。结果表明:①具有明确原因的变异源中,总粒相物的变异性最大,为42.0%;总粒相物和滤片含水量(W&W)的变异性较大,为30.6%;空白水分变异性为25.3%;烟碱和气相色谱仪引入的变异性仅占2.3%;在进行减小测量变异性改进时应从前3个变异源考虑;②由日期和时间引起的变异性为42.9%,在卷烟焦油比对测试时应参考日期和时间方向上的变异进行设计。To study the differences of various variation sources in the determination of tar content in cigarette smoke,nested variance analysis and nested factorial design analysis were applied.The results showed that： 1） Of all the definite variation sources,total particulate matter had the greatest variation of 42.0%,followed by moisture content in total particulate matter and Cambridge filter（WW）,and that in blank filter,their variation was 30.6% and 25.3%,respectively;the variation introduced by nicotine and gas chromatography was only 2.3%.Therefore,the first three variation sources were of importance for reducing measurement variation.2） The variation induced by time was 42.9%.So it is a factor should be taken into account in design of comparison test of cigarette＇s tar content.
