Mariners were also able to fix their latitude, by using an instrument called an astrolabe.(海員們還可使用星盤這種儀器確定緯度。)

A study of the rule of the diurnal variation of latitude and longitude, obtained with the astrolabe in Shanghai, leads us to the hypothesis that the diurnal var...(在此基礎上求出了組間差變化率曲線，進而分析研究了上海地區等高儀經緯度測量值周日變化的規律。)

The observing result of a photo electric astrolabe is largely affected by the processing method of photo counting data.(在光子計數資料的處理方法設計不完善時，有可能會大大影響光電等高儀的觀測結果。)

On the astrolabe, an off - centered circle represents the orbit of the sun - the ecliptic.(在星盤上，一個偏心的圓代表了太陽的運行軌道——黃道。)

The astrolabe had long been the primary instrument for navigation, having been introduced in the eleventh century.(自11世紀星盤被引入以來，它一直都是航海的重要工具。)
