( 7 ) an optimum design method for the artificial bend channel in diversion headwork of bend type by the theory of minimum rate of energy dissipation ( 7 )將最小能耗率原理應(yīng)用到低水頭彎道式引水樞紐設(shè)計中。
The vibration in the turning - point range shows a strong coupling between the membrane and bending solutions : either the membrane drive or the bending drive causes motions of both the membrane type and bending type 薄殼強迫振動呈現(xiàn)出薄膜解和彎曲解的耦合特點:無論由薄膜力還是由彎矩激發(fā),振動均俱含薄膜和彎曲運動。
