• 例句

• Previous, indirect detections of more than 300 exoplanets had provided breakthroughs of their own. 此前, 對(duì)300多顆系外行星的間接觀測(cè)都分別取得了突破.
• Thus, keeping track of the whole trajectory and the history of detections is not required. 因此保存所有的軌道以及發(fā)現(xiàn)的歷史記錄是不必要的.
• But all exoplanet detections had been of the squiggly variety. 但是此前所有探測(cè)到的系外行星都是不起眼波形.
