momentum sphere 中文意思是什麼
momentum sphere
解釋
動量球-
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。 -
In some ways, an electron is just like such a spinning sphere of charge ? an electron has a quantity of angular momentum ( its “ spin ” ) and an associated magnetism, and in an ambient magnetic field its energy depends on how its spin vector is oriented
就某種意義而言,電子可類比於一個旋轉的帶電小球:它帶有角動量(就是自旋)以及伴隨而來的磁性,而它的能量是由自旋向量與外加磁場的關系來決定。
