grain-to-grain shear stress 中文意思是什麼
grain-to-grain shear stress
解釋
粒間切應力-
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。
