为研究退休接尘矿工肺通气功能损害及其变化规律，在某镍矿对１９８１、１９８８、１９９５年３次均接受肺通气功能测定的３４名退休接尘矿工和２８名对照矿工进行了动态分析。结果表明，退休组每次测定的用力肺活量（ＦＶＣ）和第一秒时间肺活量（ＦＥＶ１）平均值均比对照组低，无论是退休组还是对照组，随着年代的后移，ＦＶＣ、ＦＥＶ１平均值的下降均有统计学意义，但无论是１９８８与１９８１年间，１９９５与１９８８年间，还是１９９５与１９８１年间，退休组ＦＶＣ和ＦＥＶ１年均下降值均比对照组大，退休组ＦＶＣ和ＦＥＶ１异常率的增加、异常程度的加重也均比对照组显著。
In order to study the impaired lung ventilation function of retired dust catcher and its variation, a dynamic analysis of 34 retired dust miners and 28 control miners who accepted pulmonary function tests three times in 1981, 1988 and 1995 was conducted in a nickel mine. . The results showed that the average FVC and FEV1 in the retired group were lower than those in the control group in both the retired group and the control group. The average of FVC and FEV1 However, no significant difference was found in the mean value of FVC and FEV1 between 1995 and 1988 or between 1995 and 1981 in both the 1988 and 1981 years, the abnormal rate of FVC and FEV1 in the retirement group Increase, the degree of abnormal increase are also more significant than the control group.
