- In order to supply a basis for uniting the reference value standard of chinese old men s hematocrit , a research is made on the relationship between the reference value of chinese healthy old men s hematocrit and five geographical factors , which are determined by the way of wintrobe laws . it is found that altitude is the main factor affecting the reference value of chinese old men s hematocrit . as the altitude increases gradually , the reference value aslo increases gradually , and the correlation is quite obvious . applying the method of mathematical regression analysis , a regression equation is given . if geographical values are obtained in some area , the reference value of chinese old men s hematocrit of this area can be reckoned by regression equation . furthermore , according to the similarity of the reference value , 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
为制定中国老年男性红细胞压积参考值的统一标准提供科学依据，收集了中国各地用温氏法测定的健康老年男性红细胞压积参考值，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老年男性红细胞压积参考值最主要的因素，随着海拔高度的逐渐增大，老年男性红细胞压积参考值也在逐渐增大，相关性很显著.用逐步回归分析的方法推导出了一个回归方程.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老年男性红细胞压积参考值.依据老年男性红细胞压积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、东北区等6个区 - This paper main divides into five portion , the main content includes : the characteristics of petrochemical industry at home or abroad , the entrails and exterior conditions of liao he petrifaction company , the actuality of technological management etc , and analysis the presence matter emphases from inaugurate management scientific research management and craftwork management three proportion
