modulus of runoff 中文意思是什麼
modulus of runoff
解釋
徑流模數-
Analyzed result on observed data shows that runoff erosivity and sediment transport modulus have a good power function ( y = mxn ) relationship. all the correlation coefficients of regression equation are bigger than 0. 9 in different watershed and power exponent b is 0. 4 - 0. 65, which average is 0. 52. and n is bigger as harness degree high
實際流域的觀測資料分析結果表明：徑流侵蝕力與輸沙模數之間有很好的冪函數（ y = mx ~ n ）關系，回歸方程相關系數均在0 . 9以上，關系式中冪指數n在0 . 4 - 0 . 65之間，平均為0 . 52 ，治理度越高， n值越大，而參數m與流域面積和治理度有關， m值隨著流域面積的增大和治理度的提高而減小。 -
The following conclusions were reached : i ) in different watershed, runoff depth and sediment transport modulus have power function ( y = axb ) relationship and the non - line regression equation can well simulate their relationship. parameter a and b can reflect difference of watershed harness degree
通過研究，取得如下結論： （ 1 ）在不同流域內，徑流深與輸沙模數均成冪函數（ y = ax ~ b ）關系，其關系方程以非線性回歸擬合結果比較好。
