本文立足於黑龍江省各種河流的洪水特點,結合以往工程實際,對影響跨河橋梁設計高度的主要因素? ?設計洪水流量及其相應洪水位的確定方法加以詳細分析。提出有約束不連序系列的加權優化適線法及適合於黑龍江省的河流粗糙系數和洪水比降的確定原則,並介紹了三日降雨量法。According to the least twin multiplication to calculating the sensitivity index in several water production functions. thus, the writer obtains the fitted the value of the sensitivity index and the varied rule. at the same time, the writer puts forward a new method named rag a ( real coding based accelerating genetic algorithm ) and combines raga with dpsa to calculating the best irrigation system under the non - sufficient irrigation of well irrigation rice in sanjiang plain
根據《隨機水文學》理論中的時間序列分析法,建立了適合三江平原井灌水稻需水量預報的非平穩時序隨機模型;通過分析降雨隨機特性,選定季節性時序隨機模型,建立了適合三江平原井灌水稻降雨預報的月平均降雨模型;根據最小二乘法,計算出幾種常用水分生產函數中的敏感指數及敏感系數,進而得到三江平原適宜採用的水分生產函數漠型及模型中敏感指數的變化規律;本文提出遺傳動態規劃法( raga ? dp ) ,即採用改進的基於實數編碼的加速遺傳演算法( realcodingbasedacceleratinggeneticalgorithm ,簡稱raga )與動態規劃法( dpsa )相結合,推求非充分灌溉條件下三江平原井灌水稻的最優灌溉制度。The main features in the study of flood forecasting and control system are as follows : ( 1 ) runoff generating and confluence theory and hydro - dynamic method are adopted to predict the water level of taihu lake and key nodes, the basin wide forecasting and control system with the function of real time correction has been first established in plain river network to meet the complicated flow conditions of taihu lake basin and to enhance the reliability of forecasting results ; ( 2 ) according to the rainfall in foreseen period multiple schemes can be made in the forecasting model and adjusted with time, which overcomes the errors caused by the uncertain rainfall in the foreseen period so as to make the forecasting results approach reality
本文所研究的預報調度系統有如下特點: ( 1 )本系統採用產匯流理論和水動力學方法預報太湖及重要節點水位,首次在平原河網地區建立了具有實時校正功能的全流域預報調度系統。以適合太湖流域復雜的水力條件,增強預報的可靠性; ( 2 )預報模型可以根據預見期降雨量進行多方案預報,並隨時間推移,可以實時進行調整,克服由於預見期降雨不確定引起的誤差,使預報結果更接近實際。The instantaneous unit hydrograph theory would be suitable for the high antecedent baseflow and the high rainfall intensity to estimate the direct runoff, but it still needs to prove its fitness with much more cases
在臨前基流量較大或降雨強度較大時,應用瞬時單位歷線理論分析逕流特性之準確性較高,然確實之適用條件仍有待進一步之研究。Distinct changing features of clouds after seeding were analyzed, then some significant conclusions are got. with the suitable seeding methods in proper time and region in clouds, precipitation is enhanced. and spacial distribution is changed, for example, position of rainfall center and intensities were significantly changed
研究發現不同催化劑對雲體的影響各有其自身特色,但也有共同之處:在雲體發展的合適時機和部位進行適量的催化,地面累積總降水量提高;同時有可能改變降水的空間分佈,使地面雨量中心位置和強度發生改變。分享友人
