在太空中製造的船艦在無重力狀態下要怎麼測量噸位？
|
其實, 噸位跟排水量很容易誤導人, 排水量還好... 大家都會想到是重量
但是噸位... 實際上指的是船的內部容積, 換算成能裝多重的水 XD
船的重量有兩種算法, 一種就是排水量 displacement, 起源於阿基米德著名的辨別王冠實驗,
另一種就是, 所謂空重, lightship 或是 lightweight, 是指船在空載測的重量, 可能是在船塢理測量的

Cain was the first man ever to strike down another... and when the Lord came to him and said ‘What have you done!?’, Cain could not hide his crime. For the voice of his brother’s blood cried out from the very ground
The world has been your battlefield, everywhere you go. The blood of brothers and sons screams out against you. Perhaps you cannot yet hear it, because the soil is not your own, but you will... you will
