摘　　要：目的　探讨脑血栓的发病是否与气象因素有关。方法　通过对 2 0 0 0年 1～ 12月哈尔滨市某大医院的脑血栓病人与气象因素的灰色关联分析 ,计算灰色关联系数r0i(k)和灰色关联度r0i。结果　脑血栓发病与气压、相对湿度、地面平均温度及平均气温的灰色关联度分别为 0 .833、0 .849、0 .5 6 6、0 .5 85。结论　气象因素对脑血栓的发生确有影响 ,气象因素对脑血栓发生的影响大小顺次为相对湿度、气压。Objective To stuty the relationship between the factors of meteorological phenomena and the disease of cerebral thrombosis.Methods Analysis of grey correlation was carried out between the factors of meteorological phenomena and the disease of cerebral thrombosis in one hospital of Harbin from January to December in 2000.We made out the coefficient r 0i (k) and value r 0i of grey correlation.Results The value of grey correlation of occurrence of cerebral thrombosis and atmospheric pressure, relative humidity, average air temperature and ground average temperature was 0.833,0.849,0.566,0.585.Conclusion We conclude that significant influence of meteorological phenomena does indeed exist.The order of the influence is relative humidity, atmospheric pressure ,average air temperature and ground average temperature.
