The results from the spirometric investigations of lung function in two comparable groups of 28 smokers and 37 non-smokers, aged at an average of 20 are presented. Positive obstructive lung alterations were established in the smokers (smoking about 20 cigarettes daily in the course of four and more years); they were confirmed by the considerable decrease of FEV1MEFR200-1200MMEFR25-75,EFR25 and EFR10. MMV50 is decreased with a limited statistical significance.
本文呈现了对两组平均年龄为20岁的可比较人群（28名吸烟者和37名非吸烟者）进行肺功能肺活量测定的结果。吸烟者（在四年及更长时间里每天吸约20支烟）出现了阳性阻塞性肺改变；FEV1、MEFR200 - 1200、MMEFR25 - 75、EFR25和EFR10的显著下降证实了这一点。MMV50有所下降，但具有有限的统计学意义。
