摘　　要：本文应用典型相关分析方法分析了大气污染、被动吸烟及燃料使用种类对174例儿童唾液溶菌酶及肺功能的影响。结果表明两组变量之间存在负相关,载荷高的变量有X_2(0.7460)、X_1(0.7221)、Y_1(-0.9665)、Y_(10)(-0.5456)、Y_9(-0.5186),说明大气污染水平、被动吸烟的数量可直接引起儿童唾液溶菌酶含量及末梢小气道的功能下降。In order to study the effects on air Pollution,Passive smoking and fuel type to 174 cases children's salivary lysozyme and pulmonary funvtions,we have analysed thesurveyed results with CANONICAL CORRELATION ANALYSIS.The results showed negative Correlation between two group variables.The weighted variables included X2(0.7460),X1(0.7221),Y1(-0.9665),Y10(-0.5456)and Y9(-0.5186).All the opposite signs indicated that declines of children's salivary lysozyme level and sma-11-airmays function were caused directly by air Pollutant levels and total numbers of passive smoking.
