There are many theories about what happened to a missing Malaysia Airlines plane,but confirmed information is hard to come by.We'll tell you what we know today on CNN STUDENT NEWS.It's been 13 days since the flight with 239 people aboard vanished over Southeast Asia.There are 26 countries involved in the search.The area is almost 3 million square miles from Eastern Europe to the Southern Indian Ocean.It even extends to the pilot's house.A flight simulator was there,and yesterday, Malaysian officials said some files have been deleted from its hard drive.Investigators are trying to recover those to see if they hold any clues,though it could be just another dead end.U.S. officials say the aircraft's most likely location is the bottom of the Indian Ocean.The big complete area is still enormous.You are still talking about an area around the size of the United States.But the area they are focused on most today is about the size of Arizona.Remember, we've talked about these two arcs out here, the northern and southern arcs.This is along the southern arcs.And they are specifically focused on this area about 1400 miles or so away from the West Coast of Australia.This is a moving target, by the way.This was bigger yesterday.You put it on the floor now.And it was a little bit further to the West,but because of drifting patterns and things like that, they adjusted with the hours.This is all based on something from mathematics called Bayesian theory,which is basically saying, as all of your parameters change hour to hour, day to day in a search,
关于失踪的马来西亚航空公司飞机究竟发生了什么有许多传言,但罕有获得证实的信息。在今天的CNN学生新闻中会为你带来我们所知。自从这架机上载有239名乘客的航班在东南亚消失已经经过了13天。有26个国家投入到了搜索当中。从东欧到南印度洋面积近300万平方英里。调查甚至延伸到了飞行员的住所。因为在他家有台飞行模拟器,而在昨天,马来西亚官员称一些文件已被从硬盘中删除。调查人员们正试图恢复那些数据以找到是否留有任何线索,尽管这可能只是另一个死胡同。美国官员表示这架飞机最可能的位置是印度洋底。这一完整区域面积仍然十分巨大。你在谈论的是一个美国大小的区域。但是他们今天最为关注的是亚利桑那州大小的地区。请记住,我们在这里谈论的是这两个弧,南北两个弧形地带。这一条是沿着南部弧形地带。他们特别关注的这个地区是距离澳大利亚西海岸大约1400英里的地方。顺便一提,这是一个移动的目标。昨天这是更大的区域。你现在将它放在地板上。有点向西,但是因为还有漂流之类的形式,他们只能用时间调整。这都是基于数学上被称为贝叶斯的理论,它的基本原理是因为你所有的参数每天在搜索中天天，时时变化,
