摘　　要：目的应用圆形分布法分析我院麻疹病例住院高峰期变化。方法选取我院2000与2001年麻疹病例累计数据与2010年麻疹病例数据应用圆形分布法进行数据处理和分析。结果本文通过应用圆形分布法分析，发现2000-2001年麻疹分布高峰日为3月18日，高峰期为元月23日至5月11日；2010年麻疹分布高峰日为5月6日，高峰期为3月26日至8月17日；2000-2001年和2010年麻疹住院高峰期分别是3月18日和5月6日，经统计学检验，F=119．37，P〈0．01，差异具有统计学意义。结论圆形分布法对具有圆形分布的数据是一种很好的定量分析方法。通过以上分析我们可以得出麻疹住院高峰期在我院发生了一定变化，该结果将为管理决策提供科学准确的可用信息。Objective To analyze variation of inpatient peak in my hospital using the circular distribution. Methods Accumulative data of measles cases in 2000 and 2001 and data of 2010 were selected and analyzed by using circular distribution. Results The inpatient peak day was the eighteenth of March in 2000 and 2001 and the inpatient peak period was from twenty- third of January to eleventh of May. The inpatient peak day was the sixth of May in 2010 and the inpatient peak period was from the twenty- sixth of March to the seventeenth of August. After statistical testing, there was significant difference with F = 1 I9. 368 3, F0.01 （ 1 950） = 6. 69, F〉 6.69 and P〈0.01. Conclusion Circular distribution method is a very good quantitative analysis method for data of circular distribution statistics. Above analysis shows that some variation is found in measles inpatient peak, and can provide messages for decision-making and management scientifically and accurately.
