drawdown level 中文意思是什麼
drawdown level
解釋
水位降深-
( 4 ) the maximum water quantity becomes greater, the better is the filtering bed permeability, the higher the river hydraulic conductance, the higher the river level, the larger the water - collecting area and the bigger the distance between collecting pipes. the water quantity varies directly with drawdown
（ 4 ）濾床的滲透性能越好，河床水力傳導系數越高，河水水位越高，取水面積越大，取水管之間的間距越大，則最大取水量越大；水位降深與取水量成正比關系。 -
Based on the analyses of the relationship between the power generation and the stored energy of multi - year regulating storage reservoirs, a fuzzy multi - objective decision - making model for year - end drawdown level of multi - year regulating storage reservoirs in cascade reservoirs is developed
摘要在分析多年調節水庫水電站發電量與水庫蓄能量關系的基礎上，建立了確定梯級水庫中多年調節水庫年末消落水位的模糊多目標決策模型。 -
With this model, the optimal year - end drawdown level of multi - year regulating storage reservoir and corresponding optimal power generation of every cascade hydropower station for certain weighted factors can be calculated
求解該模型可得到在給定權重下多年調節水庫的年末水位及各級水電站相應的最優發電量。
