Each subjects lung function was measured by Vitalograph as the machine which recorded the measure value, predict value according to the six, age and hight of the subject. FYCC (FVC meaure value/FVC predict value), FEV1 (FEV1 measure value/FEV1 predict value) and FEV1- FVCM (FEVl/FVC) were used as indicators for luug function in the paper and the demarcation between normal and poor lung function was 80% for FVCC and FEV1C while 75% for FEV1FVCM of predict value. The investigation results showed that the workers could pay more attention to food and health.
