煤粉及其燃烧后能产生的两类生物活性不同的粉尘。对电厂碎煤、运煤粉接触的煤尘,炉膛维修和清理接触的炉灰尘对作业工人肺功能阻塞性影响分析报导尚少。为有效地加强劳动卫生监护措施,作者应用大、小气道通气功能综合评价方案-(?)=-0.4324+0.0075X_2+0.0145X_2[式中:X_2代表 MMEF%(实测值/应有值%),X_2代表 FEVO/FVC%;代表由 X_1与
Pulverized coal and its combustion can produce two types of biological activity of different dust. There is little report on the obstructive influence of pulmonary function of working workers on coal dust, coal dust in contact with coal-fired power plant, furnace repair and dust contact with clean-up workers. In order to effectively strengthen the monitoring measures of labor hygiene, the author applied the comprehensive evaluation program of large and small airway ventilation function - (?) = - 0.4324 + 0.0075X_2 + 0.0145X_2 [where: X_2 represents MMEF% (measured value / due value%) , X_2 represents FEVO / FVC%; represents by X_1 and
