摘要
本文在某镍矿对201名接尘不吸烟退休矿工和108名不吸烟对照工人进行了肺功能的测定与分析。结果表明：接尘不吸烟退休矿工FVC、FEV1、FEF25%-75%的实测值、实测值占预计值的百分比均显著低于对照工人，异常率则高于对照工人，且差异具有显著性。配对研究结果显示：接尘不吸烟退休矿工FVC、FEV1、FEF25%-75%的平均实测值低于对照工人，异常人数则较对照工人明显增高，经检验均具有统计学意义。
A cross-sectional study of pulmonary function was conducted on 201 retired nonsmoking nickelminers and 108 nonsmoking control workers. The results showed that the retired group had lowerlevel of measured value and percentage of predicted lung function in FVC,FEV,,FEF25%-75%, thancontrol workers,and abnormal rates of lung function in the retired group were higher. Meanwhile amatched study was performed,the same results have been also obtained.
