本文对134名健康成人作最大呼气流速—容量(MEFV)作了测定.按男、女性别及各年龄组分别计算了75%、50%及25%肺容量的流速(V_(75)、V_(50)、V_(25))和V_(50)/V_(25)比值.V_(50)、V_(25)与年龄、身高、体重、体表面积的相关系数也作了计算,并且指出V_(50)、V_(25)与年龄呈负相关.作了男、女性的V_(50)、V_(25),V_(50)/V_(25)正常预计值回归方程式及显著性测验. The maximum expiratory flow volume-volume (MEFV) was measured in 134 healthy adults.The rates of V (75), 75%, 50%, and 25% V 50 and V 25 and the ratio of V 50 / V 25 were also calculated.The correlation coefficients of V 50 and V 25 with age, height, body weight and body surface area were also calculated and pointed out V_ (50) and V_ (25) were negatively correlated with age, and regression equations and significance tests of V_ (50), V_ (25) and V_ (50) / V_ (25)
