英文翻譯 星體運動相關

The regular motion of the stars is very suitable for forming the basis for another system of time reckoning, which is know as sidereal time. For any given place, it is defined as the right ascension of the stars that are on the meridian at that particular instant. Because of this definition, sidereal time may be determined directly by observation of the sky.

規律運行的星體非常適合另一個時間推算的系統,這個系統可以得知恆星時(sidereal time)。任何位置下,定義為星體在經線上特定瞬間的變化。因為這個定義,恆星時可以透過觀察天空來確定。

Update:

麻煩幫我修正一下

灰底部分代表不確定

    此段在闡述「恆星時」的定義,也就是說,同一顆恆星相鄰兩次過中天的時間是一「恆星日」。

    ※ 赤經在子午線上也就是「中天」的意思
