双语新闻：澳总理：无人潜艇可能一周内结束失踪客机搜寻 Australia PM:Submarine Could Finish Current Search for Malaysian Jet in a Week

澳大利亚总理阿博特说，在印度洋海底搜寻马航失踪客机的“蓝鳍21”无人潜艇将在一周内结束搜寻行动。

阿博特对华尔街日报说，如果“蓝鳍21”在一周内没有发现失踪客机残骸，有关当局将停止搜寻，重新进行部署，并考虑下一步如何行动。

澳大利亚搜寻行动协调中心星期四说，“蓝鳍21”首次完成了16个小时全程搜寻马航失踪客机的任务，此前两次海底搜寻都提前结束。

到目前为止，“蓝鳍21”搜寻了90平方公里的海底。但有关当局说，从无人潜艇获得的声纳数据中没有发现任何有价值的线索。

美国海军官员曾经警告说，“蓝鳍21”可能需要长达两个月来搜寻6百平方公里未经测绘的海域。

Australian Prime Minister Tony Abbott says a robotic submarine scanning the Indian Ocean floor for the missing Malaysian jetliner will finish its current search within a week.

Mr. Abbott told the Wall Street Journal if the so-called Bluefin-21 submarine does not find any wreckage by then, authorities will stop, regroup, and reconsider how to proceed.

The Australian agency coordinating the search said Thursday the vehicle completed its first full 16-hour mission after two previous missions were cut short because of technical problems.

The Bluefin-21 has so far searched 90 square kilometers of the ocean bed. But authorities say they have found "no significant detection" in the sonar data collected.

U.S. Navy officials had previously warned it could take up to two months for the submarine to scan the current 600-square kilometer search area.
