本文对200名男性吸烟者、不吸烟者(各100名)的动态肺呼吸功能,进行了测量分析,结果表明:嗜烟对人体肺呼吸功能的多个指标,都有明显的影响。表现在嗜烟者的 VC肺活量),PF(呼气最高流速—气量),FV(呼气流速—气量),PEV_(1.0)(用力呼气第一秒(量),都比同年龄组的不吸烟者为小,其组间差异又均有明显意义(P<0.05)和极明显性 In this paper, the dynamic lung respiration of 200 male smokers and 100 non-smokers were measured and analyzed. The results showed that smoking cigarettes had significant effects on multiple indicators of lung respiratory function. (VC expiratory volume of the addicts), PF (expiratory flow-volume), PEV 1.0 (forced expiration for the first second) were higher than those of the same age group Non-smokers were small, the differences between the groups were significant (P <0.05) and very obvious
