  1. However, according to ann ' s theory, making use of visual basic development tool, friendly - interface single output three layers " artificial neural network generator base on improved bp algorithm has been developed by the author, and after constructing the model, the value of d _ ( cmax ), finally the gross bed - load transport rate of non - uniform sediment with a wide distribution in flume experiment of stead sediment transportation have been forecasted

    筆者採用的途徑則是根據人工神經網路理論，利用vb開發出界面友好、基於改進bp演算法的多輸入單輸出三層神經網路生成器軟體，並採用該生成器建模，對平衡輸沙狀態下的水槽輸沙試驗的d _ （ cmax ）和總輸沙率進行預測計算。
  2. The application study of improved bp algorithm in sediment science - using two set of experiment data mentioned above, the value of d _ ( cmax ) and gross bed - load transport rate in non - uniform sediment with a wide distribution in flume experiment of stead sediment transportation have been forecasted by ann generator

    改進bp演算法在泥沙科學中的應用研究?將收集整理后的兩次水槽試驗實測資料作為數據來源，利用生成器生成網路對水槽平衡輸沙試驗中的最大起動粒徑和總輸沙率進行預測。
  3. Ann is a adaptive and non - linear dynamic system made from superposition of many simple components which we call neuron. the question for computation of d _ ( cmax ) belongs to incipient motion of sediment in essence, which is the same question with two different sides, because computation of critical condition ( including critical velocity critical shear stress critical power ) for a grain size under a bed - load condition is equal to computation of a grain size during incipient motion under the bed - load condition and the water flow condition given before. and computation of gross bed - load transport rate has great relationship with standard of incipient motion

    對于d _ （ cmax ）的推求，在本質上還是泥沙的起動問題，因為尋求某種床沙條件下某級泥沙的起動條件（如起動流速、起動切應力、起動功率）和尋求某種水流和床沙條件下的起動粒徑是同一問題的兩個方面而已；而對于推移質總輸沙率推求也和泥沙起動問題中的起動標準選擇緊密相關。
  4. Computing the maximal grain size during incipient motion d _ ( cmax ) and gross bed - load transport rate in non - uniform sediment with a wide distribution are two important indexes for description its transport law, and it is also a core question for discussion in non - uniform sediment research

    寬級配非均勻沙最大起動粒徑d _ （ cmax ）和推移質總輸沙率的推求是刻畫非均勻沙推移質輸移規律的兩個重要指標，也是研究非均勻沙運動規律的核心課題之一。
