中国男性全血粘度(230S^(-1))正常值与地理因素的关系

THE RELATION BETWEEN REFERENCE VALUE OF CHINESE MALE WHOLE BLOOD VISCOSITY(230S^(-1)) AND GEOGRAPHIC FACTORS

本文收集了中国２３个地区１５６３例健康男性的全血粘度（２３０Ｓ－１）正常值，再与五项地理因素之间的关系进行了研究，发现海拔高度是形响男性全血粘反（２３０Ｓ－１）正常值最主要的因素。随着海拔高度的增大，男性全血粘度（２３０Ｓ－１）正常值也逐渐增加。运用数学回归的方法，推导出了五个一元回归方程和一个多元回归方程．如果知道了某地的海拔高度Ｘ１、纬度Ｘ２、相对湿度Ｘ３、年均温 Ｘ４、年降水量 Ｘ５等地理因素指标，就可以用多元回归方程 Ｙ＝１０．２３ ＋ ０．０００６２９Ｘ１－ ０．０７８３Ｘ２－ ０．００４６５Ｘ３＋０．０１１６Ｘ４－ ０．００２０９Ｘ５± ０．６８来估算这一地区的男性全血粘度（２３０Ｓ－１）正常值。

In order to supply a basis to the reference value of Chinese male whole blood viscosity (230S-1) ,a comparison between the valuse of 1536 samples of helathy male whole blood viscosity(230S-1) from China's 23. areas and five geographic factors is made. 40 -100 random examples are sampled in every area,which are determined with NXE -1 Cone and Plate viscosimeter made by Chengdu Instrument Factory of China. It is found that elevation is the main factor affecting the reference values of male whole blood viscosity(230S-1). As the elevation increase .the reference value of male whole blood viscosity (230S-1) also increasesgradually. Each of the 23 areas has one reference value respectvilly and every reference value has equal weight with the method of mathmatical regression analysis,five univariate regression equations and one multivariate regression equation are given out according to the average of every reference value.
