在生产过程中工人随着劳动强度的增加,呼吸量也增加,呼吸道粉尘沉积量亦随之增多。实验证明呼吸量增加5倍,呼吸道内粉尘沉积量也随之增加2～5倍。从这一事实出发,对水泥尘肺病人的接尘量及劳动强度进行综合分析,算出它们的累积呼吸粉尘值,从中发现年平均呼吸粉尘值和尘肺发 In the process of production workers with increased labor intensity, respiration also increased, the amount of airborne dust deposition also will increase. Experiments show that breathing increased 5-fold, the amount of dust deposition in the airway also increased by 2 to 5 times. Based on this fact, we conducted a comprehensive analysis of the amount of dust and labor intensity of cement pneumoconiosis patients, calculated their accumulated dust values, and found that the annual average dust value and pneumoconiosis
