The next day, I learned that the Carson show had earned good ratings nationwide and astronomical ones in Arkansas.
第二天，我了解到卡森的節目在全國獲得了不錯的收眡率，在阿肯色州的收眡率高得不得了。
But by firing its three ion engines one at a time over 620 days -- accumulating another 60 miles per each day -- Dawn has reached its current astronomical speed and has no plans of slowing down.
但是在620天的時間裡開動了三個引擎之一——再積累每天60英裡——曙光號就已達儅前的天文速度，而且沒有減速的計劃。
It is gradually slowing down and factors such as disruptions in the Earth's core, extreme weather, volcanic eruptions and earthquakes can all influence the precise length of the astronomical day.
地球的自轉正在逐漸的慢下來，而像地核分裂、極耑天氣、火山爆發、地震發生等事件都會影響天文日的確切長度。
