作者为了比较健康人和矽肺病人的肺功能测定結果的平均值,按照职业(矿工和铸工)及X线分期(日內瓦分类法)进行了统计学的研究。第一组系520名健康成年男性工人(矿工297名和铸工223名)。第二组为1470名矽肺病人(其中矿工884名,铸工556名)。采用的肺功能指标是肺活量和第一秒时間肺活量(M. E. V. S.)。研究結果表明:(1) 相同年龄及身高的健康的矿工与铸工之間的肺功能无区別;(2) 健康人的肺活量与身高成正比,而与年龄成反比;(3) 各期矽
In order to compare the results of lung function measurements between healthy and silicosis patients, the authors conducted statistical studies based on occupations (miners and casters) and X-ray staging (Geneva classification). The first group is 520 healthy adult male workers (297 miners and 223 casters). The second group consisted of 1,470 silicosis patients (including 884 miners and 556 casters). The index of lung function used was spirometry and first-second time vital capacity (M.E.V.S.). The results of the study indicate that: (1) There is no difference in lung function between healthy miners of the same age and height and caster; (2) Vital capacity in healthy individuals is directly proportional to height and inversely proportional to age; (3) Each stage
