    摘 要:目的 为制定中国男人全血比粘度参考值的统一标准提供科学依据. 方法 收集了中国584个单位用毛细管法测定的37750例健康男人全血比粘度参考值，用曲线回归分析的方法研究了其与海拔高度之间的关系. 结果 发现随着海拔高度的逐渐增大，男人全血比粘度参考值按指数律也在逐渐的增大，相关性很显著(R=0.890);推导出了一个曲线回归模型Y =4.35×1.000132x ±1.07. 结论 如果知道了中国某地的海拔高度，就可以用回归模型估算这个地区的男人全血比粘度参考值.依据男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，中部区，东部区3个区.

    Abstract:AIM To provide a scientific basis for laying out an unified standard of the reference value of Chinese men's whole blood contrast viscosity.METHODS Reference val-ues of37750Chinese healthy men's whole blood contrast vis-cosity tested in584areas were collected.A research was made about relationship between the reference value ofChinese men's whole blood contrast viscosity and altitude by using curvilinear regression analysis.RESULTS Reference values of Chinese men's whole blood contrast viscosity gradu-ally increased by index law as the altitude gradually in-creased.The correlation was quite significant(R=0.890).A curvilinear regression model was given out:Y =4.35×1.000132x ±1.07.CONCLUSION If the altitude of a partic-ular area is known ......
