研究接尘量与矽肺发病关系,预测矽肺发病情况,对评价防尘效果,保护工人健康,制订国家粉尘容许浓度,都具有现实意义。在对铁道部长春客车厂铸钢车间粉尘浓度与矽肺发病关系的动态观察的基础上,用寿命表法,分析整理了30多年粉尘资料与矽肺累积患病概率,预测若干年后矽肺的
Studying the relationship between the amount of dust taken and the incidence of silicosis, predicting the incidence of silicosis, is of practical significance in assessing the effectiveness of dust control, protecting the health of workers and establishing the allowable concentration of dust in the country. Based on the dynamic observation of the relationship between dust concentration and silicosis incidence in the steel plant of the Ministry of Railways and the Changchun Passenger Depot, the author used the life table method to analyze and summarize the accumulated dust data and the cumulative probability of silicosis for more than 30 years. After a number of years,
