With another exhalation, lean the torso forward from the groins over the right leg.

随着另一个呼气，把躯干向前屈到右腿的上方。

As a new fashion river regulation building, it is necessary to research the effect of pile permeable groins to local flow quantitatively.

作为一种新型河工建筑物，桩柱透水丁坝对局部水流的影响亟需可靠的定量研究。

Your calves and buttocks are partners who both move forward while being resisted back by your knees and internal thighs and groins moving back.

小腿向前的动作是 轻微的 ，但你必须感觉到它。把大腿的上部往回拉这样它们在脚踝的正上方。

In order to prove water diversion and retarding action effect of permeable pile groins, the flow velocity formulas above and below the permeable pile groins are derived respectively.

为了验证井柱桩透水丁坝的分水缓流作用效果，建立单排井柱桩透水丁坝运行时的水量平衡方程，导出了单排井柱桩透水丁坝上下游流速公式。
