摆

It's hard to deliver a great hit stroke without a great backstroke.

如果没有很好的后摆，是很难打出高质量的击球的。

But to hit the ball with good quality, you have to have a good backswing.

但是要想打出高质量的击球，你一定要有好的后摆。

The only difference here is the body is more involved with rotation and the backswing is larger.

唯一的不同是身体这里需要做更多的旋转，后摆更大。

So why are we talking about the backswing?

这样一来，我们为什么要讨论后摆呢？

Tiny changes here can be felt in the backswing and lead to big improvements in the hit swing.

这里在后摆时能够感受出来的很小的改变就可以让你在击球摆动上得到很大的进步。

Its as if the backswing is stretching something, building potential energy that wants to release and fly forward.

就好象后摆是在拉伸什么东西，积聚了势能，而想要释放出来向前飞行。

This is a very effective golf exercise for eliminating or even reducing back pain and at the same time tremendously improving your backswing and follow through range of motions.

这是一个非常有效的高尔夫运动，甚至消除背部疼痛和减少，同时极大地提高你的后摆和贯彻范围的议案。

The results were as follows.(1) In the backward handspring, the trajectory of CM and horizontal velocity of CM in junior-high and college gymnasts were lower and higher than those of senior-high gymnast, so the vertical velocity is better when they perform tucked backward somersault. College gymnast has higher vertical velocity than junior-high and senior-high gymnasts in take-off moment of backward handspring phase.(2) Senior-high and college gymnasts have more elbow and shoulder angle in take-off moment of backward handspring and tucked backward somersault phase. Therefore, angle of both arm is bigger for performing in hand push away phase in the backward handspring, and increased the reaction force with body in the tucked backward handspring.(3) College gymnast has large knee flexions in hand support and push away moment in the backward handspring, it would increase rotation radius and better moments of inertia in the backward handspring.

结果显示：在后手翻阶段中，较低的重心轨迹和较高的水平速，有於后续空翻的垂直速；大专选手在后手翻阶段起跳瞬间有较高的垂直速；高中及大专选手在后手翻起跳脚地瞬间和团身后空翻起跳脚地瞬间时，肘、肩关节角皆大於国中选手，使其在后手翻起跳地瞬间时，双臂的伸展於后手翻的手推地面的动作，而团身后空翻起跳脚地时，双臂向上摆於身体向上伸展方向的掌握，并使重心有一定的腾空高；大专选手在后手翻阶段的手著地瞬间和手地瞬间的膝关节角较大於高中和国中选手，使其可增加身体的旋转半径，并能获得较佳的下摆动能，而膝关节角小则形成屈膝的动作，导致重心水平速低，减少下摆动能和影响整体动作的节奏和韵。

Mrs. Barkamb retired to a table in the window on which stood an old-fashioned mahogany desk lined with green baize, and suffering from a plethora of documents, which oozed out of it in every direction.

巴坎布夫人退到窗畔一张桌子边，那桌子上摆着一张老式的镶绿呢边的桃花心术小台架，台架上堆积的文件太多，四面八方都在溢出来。

The specific application of the system is given, for example, ballistic curve movement, rigid pendulum and reference system of movement.

以弹道曲线运动、刚性摆和运动参考系为例给出了系统的具体应用。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
