Combined with the significant project - gongboxia hydro - power station construction, emphasized on construction during flood period of power station construction period, the climate character of the upstream of yellow river basin and the practice operation state of cascade reservoirs are analyzed, some problems in construction during flood period such as flood propagation time, interval flood discharge forecast, construction risk, flood period pre - alarm and longyangxia reservoir ' s function on construction of gongboxia are also studied, with an aim at presenting real interval flood forecast scheme and dispatching method, so as to provide technological support for gongboxia hydro - power station construction period
本論文結合國家重點工程項目?公伯峽水電站的建設，以電站建設期施工渡汛為研究重點，從實施出發，分析黃河上游氣候特性和梯級水庫群的實際運行狀況，對施工渡汛中的主要問題?洪水流達時間、區間洪水預報、渡汛風險、汛期預警、龍羊峽水庫在渡汛中的作用等進行了比較全面深入的研究，目的在於提出可用於實際的區間洪水預報方案和調度方法，為公伯峽水電站施工期建設提供技術支撐。 -
Based on the historical space forecast data and corresponding actual data provided by a global semiconductor assembly and test company, the uncertainty of space planning was defined. during this analysis process, linear regression, grey prediction, neural network back propagation algorithm and confidence interval were applied, respectively, to define the uncertainty. compared with those methods, the confidence interval of historical space forecast error, calculated by mathematical statistics, was the reasonable method to define the space forecasting uncertainty
本文從半導體工廠長期生產能力計劃的頂層即廠房生產面積的計劃展開，對一跨國半導體封裝測試公司提供的廠房生產面積的長期歷史預測數據以及對應的真實數據進行分析，採用線性回歸，灰預測，神經網路bp演算法，基於數理統計的置信區間的求解等方法分別定義廠房生產面積預測的不確定度，經多種方法的比較得出，基於數理統計方法求解出的生產面積歷史預測誤差置信區間能直觀清楚地標定不確定度。 -
Moreover, a series of solution to these difficulties are brought forward : applying the theory of fold related to fault to interpret complex structural belts in piedmont : analyzing the features of the surface and underground seismic reservoir prediction and porosity model construction to predicate effectively the texture and quality of sandbodies ; using structural model to direct the construction of velocity model and process prestack migration imaging of seismic data ; utilizing interval velocity to forecast reservoir pressure : improving the drilling technology for pressure detection and prompt protection of vertical well against incline well
