基于长春地区六十年气象资料对六气起始时间的研究

Based on the Chang Chun region sixty years meteorological data to research starting time of Liu Qi

在六气起始时间理论问题讨论的基础上,通过长春地区六十年气象数据资料,建立大寒与立春2组气象数据模型。对大寒组与立春组进行独立样本的u检验,比较2组之间是否存在差异性,选取参考点对大寒日与立春日进行比较分析。结果显示,共有59个参考点,其中52个参考点分布在大寒日轴心附近,7个参考点分布在立春之日轴心附近。以长春地区气象数据资料为参考,大寒日与立春日相比较,大寒日较适合选定为六气起始时间。

According to the sixty years of meteorological data in Changchun,establish Dahan and Lichun two group model based on average temperature data,to ascertain starting time of Liu Qi. The starting time of Liuqi,establish Dahan and Lichun two group model based on average temperature data,reference to the theory of Liuqi,compare two sets of data with the Mann-whitney U test,finally select the reference point to comparative analysis the fist day of Greater Cold and Beginning of Spring. Through the Mann-whitney U test analysis,there was a significant difference between the groups Greater Cold and Beginning of Spring,the reference point is distributed mainly in the near Greater Cold Day,deviate from Beginning of Spring Day. Reference to the meteorological data in Changchun area,comparison Greater Cold Day and spring day,selected Greater Cold Day for the starting time of Liuqi.
