| 释义 | 〔Antarctica〕A continent lying chiefly within the Antarctic Circle and asymmetrically centered on the South Pole. Some 95 percent of Antarctica is covered by an icecap averaging 1.6 km (1 mi) in thickness. The region was first explored in the early 1800's, and although there are no permanent settlements, many countries have made territorial claims.
