  1. The mean duration of drought and flood events also has little secular trend

    旱澇的持續時間的長期變化也很小。
  2. Research on scaling properties of the variation of flood volume with duration

    洪量隨歷時變化的標度性質研究
  3. And a scaling lognormal model of flood volume is introduced to represent the affection of temporal scale of duration in annual maximum flood volume distributions

    並提出了洪水洪量的對數正態分佈模型來表徵年最大洪量分佈中歷時的尺度影響。
  4. Lastly, the scaling hypotheses is applied to the relationship of flood volume and duration in this paper. the flood intensity - duration - frequency form is proved based on the temporal scaling property of flood

    最後，本文將標度不變性引入洪水洪量? ?歷時關系中，對大流域年最大洪量隨歷時變化的標度性質行了嘗試性的研究。
  5. We first calculated the mean duration of drought and flood events, we found that the mean duration of drought and flood events has little spatial variability over the globe. the mean of the duration is about 1 - 1. 5 months, with a standard deviation of 0
