通过对1950~1989年间一系列有关资料进行分析，首次研究和报道了臭氧层变化、太阳活动与流行性脑脊髓膜炎及鼠疫传染病性病率流行周期特徵之间的关系。

Based on a series of analysis for the relevant data during the period of 1950~1989, the relationship between the ozone layer variation/ solar activity and the periodically prevalent features of two kinds of human infectious diseases in China, the epidemic cerebrospinal meningitis and human plagueepisodes, is presented and analyzed for the first time in this paper.

通过对1950~1989年间一系列有关资料进行分析，首次研究和报道了臭氧层变化、太阳活动与流行性脑脊髓膜炎及鼠疫传染病发病率流行周期特征之间的关系。结果表明，从较长时段看，臭氧层变化、太阳活动与ECM、HP年发病率间存在着较为密切的相关关系；从较短时段看，发病率的季节变化与某些气象因子的变化有一定的关系。此外，本文还提出了一个解释这两类疾病周期流行机制的简单模型
