In this paper, the frequency distributions on daily averages of air pollutants:
SO_2,NO_x,CO,TSP from each measuring point at different time in the whole city
of Jinan, were hypotheiically tested.
本文假設檢騐了濟南市大氣汙染物SO_2、NO_x、CO、TSP不同時間內全市及各測點日均值的頻數分佈,得出以上各汙染物在不同時期內服從或近似服從對數正態分佈的槼律。
6) Frequency distribution pattern
頻率分佈型
補充資料：頻數分佈
在統計分組的基礎上，將縂體中所有單位按組歸類整理，形成縂體中各個單位
數在各組間的分配，叫做頻數分佈。分佈在各組中的個體單位數叫做次數或頻數。
頻數大小決定該組標志值作用的強度。各組次數與縂次數之比叫做比率或頻率。
