| Abstract: |
| 对广西隆安县1969~1978年10年原发性肝癌病例地区分布资料，由Poisson分布配合法进行分析。结果认为该地区肝癌病例分布在各大队之间不呈Poisson分布，由分布类型说明肝癌地区分布不是随机的，而是有明显的集聚性，各大队之间肝癌发病有高发和低发的差别。由非Poisson分布类型提示在肝癌高度流行区内致癌因素强度在地区分布上有差别。为肝癌的病因研究提供了线索。 |
| English Abstract: |
| Poisson distribution method was used to analyse the data of a study on primary hepatocarcinoma during 1969-1978 in Longan County, Guangxi Province.The result showed that the incidence did not agree with poisson distribution at different production brigades.The morbidity at various brigades appeared quite different, suggesting the geographical distribution was not random.The fact of obvious aggregation tendency in some places implied that the carcinogen remained in different concentrations in different places. |
