常見例句雙語例句Earth's rotation rate is still slowing down--our days are getting longer and longer.地球的旋轉(zhuǎn)速度仍在減慢——我們一天的時間正越變越長。The researchers calculated how this would affect the rotation rate of the whole planet, which would compensate to conserve angular momentum.研究人員計算出這會怎樣影響整個地球自轉(zhuǎn)速度，這有助于保持角動量守恒。Since Earth’s rotation rate varies, so would the value of one second when it’s defined as a fraction of the time it takes for one spin of the Earth on its axis.由于地球自轉(zhuǎn)速率發(fā)生偏離，因此當把地球繞中軸旋轉(zhuǎn)一圈作為一個單位時，（這種偏離）就相當于一秒鐘時間。權(quán)威例句RadioAstron will also examine pulsars and the outer regions of spiral galaxies in order to get more precise measurements on their rate of rotation and distance from earth.FORBES: Russian Launch: a Bid for Largest Telescope Ever 返回 rotation rate
