Reactive power optimization is a large - scale nonlinear optimization problem with a large number of variables and uncertain parameters , the operating variables include continuous and discrete variables , so the optimization becomes very complex 電力系統(tǒng)的無功優(yōu)化問題是一個多變量、多約束的混合非線性規(guī)劃問題,其操作變量既有連續(xù)變量又有離散變量,使得優(yōu)化過程十分復雜。
In this paper , an experimental investigation of the removal of volatile organic compounds ( voc ) from dilute aqueous solutions was presented by vacuum membrane distillation ( vmd ) . experiments were carried out using aqueous mixtures of ethanol with hollow fiber module . the influences of operating variables such as feed concentration , flow rate , temperature and downstream pressure on the flux and separation factor were investigated 本文對膜蒸餾脫除水溶液中的揮發(fā)性有機化合物( voc )進行了試驗研究;文中以乙醇水溶液為研究對象,采用真空膜蒸餾法,膜材料為中空纖維膜,研究膜通量及分離因子與原料液的溫度、濃度、流速,冷側壓力的關系,并對真空膜蒸餾的傳熱傳質機理進行了初步探討。
The model control input information according as output information measure up ( related faction ) . matter - element transformation which made contradiction problem convert resolved problem exploit relevant strategy set . it make use of the strategy to solve existence problem in production controlling , thereby operating variable convert measure from fail field 該模型以控制輸出信息的合格度(關聯(lián)度)作為確定控制輸入矯正量的依據(jù),利用物元的可拓性,通過物元變換化矛盾問題為相容問題,從而開拓出有關的策略集,解決生產(chǎn)控制中存在的問題,使被控變量從不合格范圍轉化到合格范圍內。
