收集了中国８６个地区４８７０例健康成年女性的低切全血比粘度正常参考值，并对其与海拔高度、纬度、年均相对湿度、年均气温、年降水量等５项地理因素之间的关系进行了研究，发现海拔高度是影响女性低切全血比粘度正常参考值最主要的因素，随着海拔高度的增大，女性低切全血比粘度正常参考值也逐渐增大．运用数学回归的方法，推导出了５个一元回归方程和１个多元回归方程，如果知道了中国某地的地理因素，就可用回归方程来估算这一地区女性低切全血比粘度正常参考值 We collected the normal cut-off reference values ​​of 4870 healthy adult women from 86 regions in China and compared them with 5 geographical factors such as altitude, latitude, annual average relative humidity, annual average temperature and annual precipitation It is found that the altitude is the most important factor that affects the normal reference value of low cut whole blood of women. As the altitude increases, the normal reference value of low cut whole blood viscosity of female also increases gradually. Using the method of mathematical regression, five univariate regression equations and one multiple regression equation are deduced. If we know the geographical factors of a place in China, we can use the regression equation to estimate the normal reference value
