摘　　要：运用圆形分布法对涂阳肺结核病人发病季节进行分析。结果表明，据１２年资料有１０年发病高峰日在７月份，总的发病高峰日在７月８日，发病高峰期为３月８日～１０月２８日。涂阳病例登记率与圆形分布ｒ值呈正相关，与角的标准差呈负相关，与平均角无相关。提示新登记率的高低影响发病季节性强弱，而与发病高峰日的早晚无关。In order to study the seasonal distribution of smear-positive pulmonary tuberculosis incidence,the data of yearly new diagnosed smear-positive pulmonary tuberculosis during 1983～1994 in Xuzhou was analyzed with circular distribution method.The result showed that the highest peak of yearly new diagnosed smear-positive pulmonary tuberculosis incidence occurred in July in 10 of these 12 years.In 12 years,the highest peak was on July 8th,and 95% of epidemic periods began from Mar.8th to Dec,28th.There was positive correlation of the newly diagnosed rate of smear-positive pulmonary tuberculosis with ther value of circular distribution, negative correlation with angular deviation and no correlation with mean angle.It is conculuded that the diagnosed rate of new smear-positive pulmonary tuberculosis concerns with the seasonal variation and does not concern with the date of the highest peak.
