25万年前铝合金The discovery of an ancient piece of aluminium is being hailed as evidence that aliens visited Earth 250,000 years ago.
一块古代铝合金的发现，可能会作为外星人在25万年前造访过地球的证据。
The mysterious hunk of metal was found in Romania during the 1970s, when the country was under communist rule.
这块神秘的金属于二十世纪七十年代在罗马尼亚被发现，当时该国还是共产党执政时期。
Now tests at a lab in Lausanne, Switzerland, have revealed that the strange fragment of metal is made up of 90 percent aluminium and is 250,000 years old.
现在瑞士洛桑一家实验室的检测结果显示，这块奇怪的金属碎片中90%是铝，来自25万年前。
Aluminium was not produced by mankind until about 200 years ago, so the discovery of the large chunk that could be up to 250,000 years old is being held up as a sensational find.
人类近200年前才掌握生产铝的技术，所以这块来自25万年前的巨大金属块可能会是一个轰动的发现。
Gheorghe Cohal, the Deputy Director of the Romanian Ufologists Association, told local media: "Lab tests concluded it is an old UFO fragment given that the substances it comprises cannot be combined with technology available on Earth."
罗马尼亚UFO研究学会副主任乔尔吉·高亚对当地媒体说：“如果认为那个时候地球上不存在合金冶炼技术，那么实验室的检验结果就说明它是一块UFO碎片。”
Builders working on the shores of the Mures River not far from the central Romanian town of Aiud found the objects about 33 feet under the ground, where it was buried alongside two bones.
当时，在罗马尼亚中部城市阿尤德附近的罗马尼亚穆列什河岸边工作的建筑工人，在地下大约33英尺（约合10米）深的土层中发现几块奇怪的物体，旁边是两块骨头。
It was quickly determined that the two large bones belonged to a large extinct mammal that died between 10,000 and 80,000 years ago, but experts were stunned to find out that the third object was a piece of very lightweight metal and appeared to have been manufactured.
当时很快就鉴定出，那两块骨头属于现在已经灭绝的大型哺乳动物，距今已有一万到八万年时间。而专家们震惊地发现，第三块物体是一块很轻的金属，似乎是加工出来的。
However, local historian Mihai Wittenberger said the object is actually a metal piece from a World War II German aircraft, although this does not explain the age of the artifact.
不过，当地历史学家米哈伊·维滕伯格认为这块金属是二战中德国飞机的碎片，但他没有考虑金属物品的年代和二战完全不相符。
The metal object has now gone on display in the History Museum of Cluj-Napoca with its full history causing heated speculation after it was noted that museum officials had added a sign saying: "origin still unknown."
目前，这块神奇的铝合金陈列于罗马尼亚的克卢日-纳波卡历史博物馆，博物馆工作人员在其物品注释中写道“来源不明”，引发了观展热潮。
