摘要
计算尘肺病的平均发展速度方法甚少报道。本文试用切线法迭代公式计算了韶关市某钨矿1980～1989年尘肺病的平均发展速度,并对其应用作了初步探讨,取得了较为满意的效果。
To compute the average developing speed of pneumoconiosis in a tungsten mine in Shaoguan area for recent ten years, tangente method iteree model was adopted. The result seemed to be more satisfactory and its applicability was discussed. It showed that the incidence rate of pneumoconiosis in the tungsten mine decresed with a speed of 6.613 percent year by year. It was related to the effect of anti-dust measures performed by that mine.
