我国不同地理位置的红细胞压积值

A PRELIMINARY RESEARCH INTO THE RECLATION BETWEEN THE NORMAL INDEX VALUES OF HEMORHEOLOGY AND THE GEOGRAGHICAL FEATURES OF CHINA

红细胞压积是红细胞浓度的一级近似值，也是血液流变学诸因素中最重要的影响因素。我国幅员辽阔，地理环境不同，这种环境因素对红细胞压积的影响甚大。作者运用数学回归方法研究海拔高度与红细胞压积的内在规律．并计算不同地区的红细胞压积值。

For the regions with the same latitude, the value of Ht apear- antly increases along with the increase of elevation. For the regions with the same elevation, Thd value of Ht increases along with the increase of latitude (from thd south to the north); But the increase is not so appearant and has rel- apse. So the changes of elevation are the chief reason which causes thd changes of Ht, Here is a formula which tells the relation between Ht and elevation; The method adopted here is mathematicalregression and the data form the above-noted 22 regions in china. Male: Ht (M) =43.6 + 4.5× 10-3 ·h Femal:Ht ( F) =39.4 +3. 6 × 10-3 ·h In this formula, h refers to elevtion, the unit is metre.
