GATE: external direct (opposite side of the hinge). Flow direction should climb over the gasket side.

浇口：外部方向(铰链对面)。流向须爬过衬垫侧。

The method is applied to free surface sluice gate flow over spillway and computed pressure distribution agrees satisfactorily with experimental results.

用这种方式可以减少计算的工作量，算出的溢流面压力分布资料和试验结果符合较好。

To simplify (a lot) the tri-gate transistor allows power to flow over three surfaces of a tall and narrow silicon fin, rather than over a flat surface.
