If something is en pointe, it means perfect, it looks so good.

果某物是" 踮脚尖" 的，表示它很完美，看起来很不错。

What you're wearing today, that dress, your dress is en pointe.

你今天的穿着很完美。

And except for what's lost to friction, that angular momentum has to stay constant while the dancer is on pointe.

除了摩擦损耗的动量之外，当踮起脚尖时 角动量必须保持不变。

As she turns, friction between her pointe shoe and the floor, and somewhat between her body and the air, reduces her momentum.

在她旋转的过中，脚尖和地板的摩擦力，和她的身体所受到的空气阻力，会减少她的动量。

Also an electrocardiogram might have changes such as a prolonged QT, prolonged ST segment, and arrhythmias, like torsade de pointes and atrial fibrillation.

心电图也可能会发生变化，例QT延长、ST段延长，还有心律失常，比尖端扭转和房颤。

The other option is for the dancer to bring her arms or leg in closer to her body once she returns to pointe.

另一个择是当次踮脚时 将她的手臂或腿缩得离身体更近些。

Her supporting foot flattens, and then twists as it rises back onto pointe, pushing against the floor to generate a tiny amount of new torque.

她会放下支撑脚，在踮起的过中扭转，蹬地以获取 微量的新的旋转动力。

When the leg comes back in towards the body, that stored momentum gets transferred back to the dancer's body, propelling her around as she rises back onto pointe.

当腿向着身体方向缩回之时，那些储存的动量被转移回到身上，当她次踮起脚尖时 动量推动她旋转。

If they go to a lovely, sunny beach, the boyfriend is there for hours taking hundreds of pictures until he gets the one that looks...looks en pointe and looks perfect.

果他们去一个可爱的、阳光明媚的海滩，果他们去一个可爱的、阳光明媚的海滩，男朋友会在那里花上几个小时拍摄数百张照片，直到他拍到一张看上去很不错、很完美的照片为止。
