ergosphere

ergosphere

1. 2.When a black hole absorbs a star, the star is first pulled into the Ergosphere, which sweeps all the matter into the Event Horizon.

当黑洞吸入恒星时，恒星先是被吸到能层，能层又将所有的物质卷进事界。

2. Objects grazing the ergosphere could in some circumstances be catapulted outwards at great speed, extracting energy (and angular momentum) from the hole, hence the name ergosphere ("sphere of work") because it is capable of doing work.

擦过能层的物体就会在某个情形下以极大的速度弹射出去，从黑洞里提取能量（与角动量），因此叫能层（“做功的球）因为它有能力作功。

3. However, because space-time itself is moving in the ergosphere, it is impossible for objects to remain in a fixed position.

然而因为时空本身是在能层里移动，物体保持在固定位置是不可能的。

4. Since the ergosphere is located outside the event horizon, objects can exist within the ergosphere without falling into the hole.

物体可以存在于能层内而不落进洞里。

5. ergosphere effect

能层效应

6. This spinning area surrounding the event horizon is called the ergosphere and has an ellipsoidal shape.

这活动视界周围旋转的区域是所谓的能层而具有椭圆形。
