| 摘 要： | 运用相关分析法研究中国健康成年男性肺一氧化碳弥散量参考值与海拔高度、年日照时数、年平均气温、气温年较差、年平均相对湿度、年降水量、年平均风速、年平均总云量关系.海拔高度是影响成年男性肺一氧化碳弥散量参考值最主要的因素.以多元回归分析理论为基础,构造趋势面回归数学模型.应用GIS内插成年男性肺一氧化碳弥散量参考值空间趋势图,知晓中国某地地理坐标,用此模型可估算该地成年男性肺一氧化碳弥散量参考值,从空间趋势图可得任意地区肺一氧化碳弥散量参考值.

| Abstract: | A research is made about the relationship between the normal reference value of 15549 cases of Chinese adult men's diffusion capacity for carbon monoxide of lung(DLCO) and altitude,annual sunshine duration,annual mean air temperature,annual range of air temperature,annual mean relative humidity,annual precipitation,and annual mean cloud cover in China,which are determined by the way of single breath method,using the methods of correlation analysis.It is found that altitude is the main factor affecting the r... |
