On The Relation ship of Atmospheric Pollution to Cancer by the Mathematical Statistics Method
【摘要】 用数理统计方法以某市近 6年期间发现的 2 2 90个肿瘤病例为依据 ,定量地解决了 SO2 、香烟销售量、COD、T· S· P对肺癌等 7种癌病的影响大小 ,从而解决了不同污染区 ,不同癌病有目标地重点解决大气污染治理投资问题
【Abstract】 Based upon 2 ,2 90 tumorcasesfound in a city in recentsix years,thispaper,by the mathematical statistics method,quantatively solves how much SO2 ,the amount of cigarettes in sale,COD and T· S· P affect seven kinds of cancer such as lung cancer,thus solving the problem of investment to bring atmospheric pollution under control based on differentpolluted areas and cancers to the point.
