澳大利亚确信声音信号来自马航失踪客机

Australian authorities say they are confident that underwater signals detected in the search for missing the Malaysian jetliner are from the airplane's black box recorders.

Australian Prime Minister Tony Abbott told reporters in Shanghai Friday that search crews looking for the plane have narrowed down that patch of Indian Ocean where they are searching for the sounds.

Mr. Abbott briefed Chinese President Xi Jinping on the status of the search. Some two-thirds of the passengers onboard the flight were Chinese.

Pings consistent with a flight data recorder have been detected by an Australian ship that is using a U.S. naval device to detect black boxes.

Time is running out for authorities to locate the origin of the signals, since the batteries on the black box's locator beacon are set to run out after about 30 days.

The Malaysia Airlines jet, which was carrying 239 people, disappeared on March 8 while traveling from Kuala Lumpur to Beijing.

Malaysian authorities believe the plane was deliberately diverted and crashed into the sea. But without wreckage, many are skeptical.

If authorities can locate more pings, they plan to deploy a robot submarine to search the ocean floor.

Once the black box is retrieved, authorities will be able to determine what happened to the plane. Its fate has become one of the most puzzling mysteries in aviation history.澳大利亚当局说，他们确信，搜寻失踪马航客机行动中探测到的水下信号来自这架飞机的黑匣子。

澳大利亚总理阿博特星期五在上海对记者说，搜寻人员收窄了在印度洋搜索的范围，他们目前正在那一带搜索声音信号。

阿博特向中国国家主席习近平简要介绍了搜寻的进度。这架失踪客机上大约三分之二乘客是中国人。

澳大利亚海军使用美国海军探测黑匣子的设备探测到了跟飞行数据记录仪一致的信号。

鉴于飞机黑匣子定位仪信标的电池在大约30天后将耗尽，当局应该尽快确定发出信号的方位。

载有239人的这架马航客机3月8日在从吉隆坡飞往北京的途中失踪。

马来西亚当局认为，这架客机被蓄意转向，然后坠入大海。不过找不到飞机残骸，这让许多人持怀疑态度。

如果当局能够探测到更多信号声，他们计划部署水下机器人，到海底探查。

一旦黑匣子被复原，当局就能确定这架客机失踪的原因。马航370客机的失踪成为航空历史上最令人费解的迷之一。
