摘　　要：以华北地区A市为例,分析日不均匀系数的分布规律。通过数理统计的方法,检验2002—2012年供暖期日不均匀系数的分布规律,得出供暖期各月日不均匀系数呈正态分布。给出不同不保证率下的日高峰系数,与实际数据校核,具有较高的精度。The distribution of uneven factor of daily consumption is analyzed by taking a city in North China for example. The distribution of uneven factor of daily consumption in heating periods from 2002 to 2012 is verified by mathematical statistics methods. It is found that the uneven factor of daily consumption in every month of the heating periods shows the normal distribution. The maximum uneven factor of daily con- sumption under different risk levels is given and has a higher precision compared with the actual data.
