摘要
为制定中国青年人全血比粘度参考值的统一标准提供科学依据，收集中国各地用毛细管法测定的健康青年人全血比粘度参考值，并对其与地理因素的关系进行了研究，发现海拔高度是影响青年人全血比粘度参考值最主要的因素，用多元回归分析的方法推导出了２个回归方程。如果知道了中国某地的地理因素，就可以用这两个回归方程估算这个地区的青年人全血比粘度参考值。依据青年人全血比粘度参考值与地理因素的依赖关系把中国分为青藏区、西南区、西北区、东南区、华北区、东北区共６个区。
In order to supply a basis for uniting the reference value standard of Chinese young people's whole blood contrast viscosity, a research is made about relationship between the reference value of Chinese healthy young people's whole blood contrast viscosity and five geographical factors. It is found that altitude is the main factor affecting the reference value of Chinese young people's whole blood contrast viscosity. As the altitude increase gradually, the reference value of Chinese young people's whole blood contrast viscosity also increase gradually, the correlation is quite obvious. Applying the method of mathematical regression analysis, two regression equations are given out. If geographical values are obtained in some areas, the reference value of Chinese young people's whole blood contrast viscosity of this area can be reckoned using regression equations. Furthermore, according to the similarity of the reference value of Chinese young people's whole blood contrast viscosity, taking the altitude as the main dividing basis and considering effects of other geographical factors and population distribution, China can be divided into six regions: Qingzang, Southwest, Northwest, Southeast, North and Northeast region.
