ergosphere 中文意思是什麼
ergosphere
解釋
能層-
Anything inside the ergosphere will be dragged by the black hole and rotate with it but it can still escape
在能層內的物質會被黑洞自轉所帶動，但仍有機會逃離黑洞的魔掌。 -
If we send something to the inside of the ergosphere, and split it up into two parts, one goes in the black hole while the other comes out. if we correctly arrange the splitting, the part coming out can be made to have a much higher speed, hence higher energy
方法是把一件物體放進能層，然後把物體分成兩部分，讓一部分墮進黑洞，另外一部分逃離黑洞若我們適當地選擇它們的質量分離的時間等等便可以讓逃離的部分以更高速度即更高能量離開黑洞。 -
This spinning area surrounding the event horizon is called the ergosphere and has an ellipsoidal shape
這活動視界周圍旋轉的區域是所謂的能層而具有橢圓形。 -
However, because space - time itself is moving in the ergosphere, it is impossible for objects to remain in a fixed position
然而因為時空本身是在能層里移動，物體保持在固定位置是不可能的。 -
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
擦過能層的物體就會在某個情形下以極大的速度彈射出去，從黑洞里提取能量（與角動量） ，因此叫能層（ 「做功的球）因為它有能力作功。
