An astrolabe is an instrument that was used for centuries to mark the positions of the sun and stars.

星盘是数百年来用来标太阳和恒星位置仪器。

The astrolabe sometimes seems to have more personality than the monk, probably because of the paucity of biographical information available.

星盘有时似乎比这个修士更有个性，但也可能是因为关于修士资匮。

The astrolabe had to be kept in a freshwater bath for two years to get all the salt off it.

The place is stored with great variety of sextants, quadrants, telescopes, astrolabes, and other astronomical instruments.

Instruments called an astrolabe and a cross-staff could measure latitude—how far north or south from the equator the ship was.

称为星盘和十字杆仪器可以测量纬度——这艘船离赤道有多远。

They were first used by astronomers hundreds of years B.C. and sailors used them in the Middle Ages until astrolabes were replaced by sextants.

公元前数百年，天文家首次使用它们，水手们在中世纪使用它们，直到六分仪取代了星盘。

Over the next 4000 years, humans developed all sorts of clever computing devices, like the astrolabe, which enabled ships to calculate their latitude at sea.

在接下来4000年种，人类开发了各种聪明计算设备例如星盘，可以使船只在海上计算其纬度。
