( 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 ）将最小能耗率原理应用到低水头弯道式引水枢纽设计中。
3.
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 薄壳强迫振动呈现出薄膜解和弯曲解的耦合特点：无论由薄膜力还是由弯矩激发，振动均俱含薄膜和弯曲运动。
