中国男性全血粘度（5．75s^（－1））正常值与地理因素的关系

Discussion on the relation between normal value of chinese male whole blood viscosity (5.75 s￣(-1) and Gegraphical factors

分析了中国２２个地区１４８３例健康男性全血粘度（５．７５Ｓ－１）正常值与５项地理因素之间的关系，发现海拔高度是影响男性全血粘度（５．７５Ｓ－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（５．７５Ｓ－１）正常值也逐渐增大．

A comparison is made between the normal values of 1483 examples of healthy male whole blood viscosity (5.75 s-1) and five geographic factors in china's 22 areas, which are determined with NXE-1 Cone and plate viscosimeter made by chengdu Instrument fatory of China. It is found that elevation is the main factor affecting the normal values of male whole blood viscosity (5.75 s-1). As the elevation increases, the normal value of male whole blood viscosity (5.75 s-1) also increases gradually. Applying the method of mathematical regression analysis, five formulae are given of univariate regression equations and a formula of multivariate regression equation. If geographic index values are obtained in some area, the normal value can be reckoned of male whole blood viscosity (5.75 s-1) of this area using the regression equations.
