摘要
采用我国19岁以下不同年龄组人群肺通气量基础数据,用曲线拟合的方法,拟合了人群累积吸气量的曲线方程式(Y=754.37+258.34X1.9038)。经检验,曲线配合适度良好(R2=0.9974)。为估算儿童和青少年人群对大气污染物的累积暴露量及对人群资料用计算机分析处理提供一个简便、实用的方法。
A fitting power curve equation based on the breath frequency and body weight for the accumulative inhaling volume in Chinese under 19 years old was established. The equation is =754 37+258 34 X 1 9038 ,and the fitting is good( R 2 =0 9974).It is useful for estimating the degree of exposure to air pollutants of people in their young period.
