摘　　要：对41例被测试者(一组为通气功能正常,另一组为通气功能异常)的通气、残气和弥散功能在两种肺功能仪进行随机测试分析。两种肺功能仪测定值之间差异均不显著(P＞0．05．通气功能正常组DLCO、FEF25、FEF75,通气功能异常组FVC除外)。两组的相关系数r＞0．9(通气功能正常组MMF的r=0．7725．RV的r=0．808,通气功能异常组FEF75的r=0．58除外),p＜0．001．非常相关。两种不同测定原理的仪器大多数测定值差异不显著,具有很好的相关性。This paper introduces a random measurement alalysis of ,lung function measurement values with two different apparatus. in 41 patients. It shows that the differences are not statistically significant （P〉0.05） between two aparatus measurement values except DLCO, FEF25, FEF75 in the group of normal ventilation, FVC in the group of abnormal ventilation. The two groups are both correlated closely （r 〉 0.9） except MMF（r=0.7725, RV r=0.808） in the normal group of ventilation, and FEF75 （r=0.58）in the abnormal group of ventilation （p〈0.001）. The two apparatus with different measuring theories have a good correlation.
