中国健康老年人全血比粘度参考值与地理因素的一元回归分析

Linear regression analysis between reference value of Chinese healthy old people's whole blood contrast viscosity and geographicalfactors

为对中国健康老年人全血比粘度参考值的统一标准的制定提供科学依据，笔者收集了中国各地用毛细管法测定的健康老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健康老年人全血比粘度参考值最主要的因素，随着海拔高度的逐渐增大，健康老年人全血比粘度参考值也在逐渐增大，相关性很显著．用一元回归分析的方法推导出了10个回归方程．如果知道了中国某地的地理因素，就可以用回归方程估算这个地区的健康老年人全血比粘度参考值．

In order to supply a basis for uniting the refercnce value standard of Chinese healthy old people's whole blood contrast viscosity. a research is made about relationship between the reference value of Chinese healthy old 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 healthy old people's wholeblood contras viscosity. As the altitude inceases gradually, the reference value of Chinese healthy old people's whole blood contrast viscosity also increases gradually The correlation is quite obvious.Ten regression equations are given out by applying the method of mathematical regression analysis. If geographical index values are obtained in some area, the reference value of Chinese healthy old people's whole blood contrast viscosity of this area can be reckoned by using regression equations.
