當(dāng)然，前提是物體的對(duì)稱軸存在。
The decline of brightness from its central peak along this axis of symmetry is different in the opposite directions.
在相反的延伸方向上，沿著對(duì)稱軸的亮度峰值的衰減是不同的。
Moment of inertia: turning around its axis of symmetry, object has the character keeping speed and the direction of the axis of rotation not changing.
轉(zhuǎn)動(dòng)慣性：物體在繞著自己的對(duì)稱軸轉(zhuǎn)動(dòng)時(shí)，具有保持轉(zhuǎn)速和轉(zhuǎn)動(dòng)軸方向不變的性質(zhì)。
