| 1. | And yet meridiani is not the only place where lakes appear in the orbital images 然而子午线地盘并不是轨道影像中显示的唯一湖床。 |
| 2. | The vast , flat plain of meridiani has also revealed characteristic patterns associated with waves in a shallow body of water 辽阔平坦的梅里蒂亚尼平原同样也显露出与浅水处波浪相关的特有图案。 |
| 3. | In this sense , what spirit saw at gusev is more representative of mars than what opportunity found at meridiani 这麽说来,精神号在卡西佛的观察,比机会号在子午线地盘看到的,更能做为火星的代表。 |
| 4. | Exactly three weeks later , a similar exploration rover named " opportunity " landed almost half - way around the planet in an area called meridiani planum 三周后一艘名叫"机会号"的同型探测车降落在行星的另一面叫子午线平原的区域 |
| 5. | Even at meridiani , basaltic sands lie atop the lake sediments , indicating that the site has been parched for two billion to three billion years 甚至在子午线地盘,玄武岩质的沙披覆在湖床沉积物上,显示此地已经乾涸了20 ~ 30亿年。 |
| 6. | Meridiani lies on that ancient " shoreline " and may once have been a continental shelf , cycling between dry and wet phases as the ocean ' s level changed 这说明梅里蒂亚尼平原位于古代海岸线上,也许还曾是大陆架,随着海平面的升降不断在干燥与湿润间轮回。 |
| 7. | On the other side of the planet , the signs of water that led to meridiani planum being chosen as a landing site were much subtler , making it more of a gamble 而位于星球另一侧的梅里蒂亚尼平原曾有水源的迹象却并不那么另人信服,这使得选择它为着陆地点,看起来多少像是一场赌博。 |
| 8. | Rather than being a standing sea slowly accumulating sediment , meridiani seems to have the characteristic chemistry of transient lake beds in a terrestrial desert , or salt flats on a seashore 梅里蒂亚尼平原的化学表征使它看上去更像是内陆沙漠中短期存在的湖泊的沉积矿,或海岸上的盐带平地,而非长期存在的海洋中缓慢聚集的沉积物。 |
| 9. | But these patterns present a bit of a puzzle : unlike gusev crater , where the raised rim would have allowed a deep lake to form , meridiani planum has no apparent edge to the north , nothing to keep water from draining away 不过,这些图案却带来了个小小的难题:不像古谢夫盆地具有可供深湖形成的突起边界,梅里蒂亚尼平原的北方没有明显边界,没什么可以阻止水一点点地流尽。 |
