澳大利亞確信聲音信號來自馬航失蹤客機

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.澳大利亞當局說，他們確信，搜尋失蹤馬航客機行動中探測到的水下信號來自這架飛機的黑匣子。

澳大利亞總理阿博特星期五在上海對記者說，搜尋人員收窄了在印度洋搜索的範圍，他們目前正在那一帶搜索聲音信號。

阿博特向中國國家主席習近平簡要介紹了搜尋的進度。這架失蹤客機上大約三分之二乘客是中國人。

澳大利亞海軍使用美國海軍探測黑匣子的設備探測到了跟飛行數據記錄儀一致的信號。

鑑於飛機黑匣子定位儀信標的電池在大約30天后將耗盡，當局應該儘快確定發出信號的方位。

載有239人的這架馬航客機3月8日在從吉隆坡飛往北京的途中失蹤。

馬來西亞當局認爲，這架客機被蓄意轉向，然後墜入大海。不過找不到飛機殘骸，這讓許多人持懷疑態度。

如果當局能夠探測到更多信號聲，他們計劃部署水下機器人，到海底探查。

一旦黑匣子被複原，當局就能確定這架客機失蹤的原因。馬航370客機的失蹤成爲航空歷史上最令人費解的迷之一。
