美军将进行大爆炸试验 拉斯维加斯再现蘑菇云

　　新华网消息 美国五角大楼官员30日透露，美军将于6月2日在内华达州引爆700吨常规高爆炸药，意图测试摧毁深藏地下坚固目标的武器性能。 试验将在拉斯维加斯西北65英里处地区进行，试验的主要目的是检测地面爆炸对地下深层坑道建筑的冲击影响。据称这次爆炸形成的烟尘将上升至1万英尺高空。美国“国防威胁防范署”主任詹姆斯·泰格尼利亚说，自上世纪60年代初美军在内华达州停止核武器地上试爆以来，人们将首次在拉斯维加斯上空看到蘑菇云。

　　近年来，美军高官一再声称，美国潜在敌人的地下核、生、化武器库以及指挥中心越修越深，而且更加坚固，美军现有的武器已经难以穿透这些地下堡垒。因此美军已着手研制新型钻地武器，甚至考虑研发攻击地下深层加固掩体的核弹头。

　　泰格尼利亚还透露，由于这次爆炸威力巨大，美国官员已经向俄罗斯政府通报。内华达州一些民主党参议员就这次爆炸试验表示，他们担心爆炸引起的大量烟尘和有毒物质会污染环境。（万宏）

　　WASHINGTON， March 30， 2006 (AFP) - The US military plans to detonate a

　　700-tonne explosive charge in a test called "Divine Strake" that could send a

　　mushroom cloud over Las Vegas， a senior defense official said Thursday.

　　"I don't want to sound glib here but it is the first time in Nevada that

　　you'll see a mushroom cloud over Las Vegas since we stopped testing nuclear

　　weapons，" said James Tegnelia， head of the Defense Threat Reduction Agency.

　　Tegnelia's remark at a breakfast with defense reporters set off shock waves

　　of its own here.

　　"Anytime an administration official starts talking about mushroom clouds

　　and Las Vegas， I want answers，" Representative Shelley Berkley， a Democrat from

　　Nevada， said on the floor of the House of Representatives.

　　She said Tegnelia told her a mushroom cloud would not be seen "over" Las

　　Vegas， only "from" Las Vegas， according to a statement from her office.

　　DTRA also issued a statement later in the day that said "the experiment"

　　posed no environmental or health hazards， and stressed that it was not a

　　nuclear test.

　　"All explosives， given the right thermal characteristics， will create a

　　cloud that may resemble a mushroom cloud，" the agency said.

　　"The dust cloud from Divine Strake may reach an attitude of 10，000 feet and

　　is not expected to be visible from Las Vegas，" it said.

　　The agency said no radioactively contaminated soils are in the vicinity of

　　the proposed detonation site， which is over an existing tunnel at the Nevada

　　Test Site.

　　Tegnelia said the test， which is scheduled for June 2， was part of a US

　　effort to develop weapons capable of destroying deeply buried bunkers housing

　　nuclear， chemical or biological weapons.

　　"We have several very large penetrators we're developing，" he told defense

　　reporters.

　　"We also have -- are you ready for this -- a 700-tonne explosively formed

　　charge that we're going to be putting in a tunnel in Nevada，" he said.

　　"And that represents to us the largest single explosive that we could

　　imagine doing conventionally to solve that problem，" he said.

　　DTRA said the charge consists of 700 tonnes of commercial ammonium

　　nitrate-fuel oil (ANFO) explosives， which is the equivalent of 593 tonnes of

　　TNT.

　　"ANFO is a commonly used blasting agent in commercial mining and commercial

　　blasting operations，" the agency said. "The purpose is to conduct research into

　　ground motion."

　　Tegnelia said the aim is to measure the effect of the blast on hard granite

　　structures.

　　"If you want to model these weapons， you want to know from a modeling point

　　of view what is the ideal best condition you could ever set up in a

　　conventional weapon -- what's the best you can do.

　　"And this gets at the best point you could get on a curve. So it allows us

　　to predict how effective these kinds of weapons ... would be，" he said.

　　He said the Russians have been notified of the test.

　　"We're also making sure that Las Vegas understands，" Tegnelia said.

　　DTRA said it did not expect the test to have an adverse impact on the

　　environment or the health of either local residents or participants in the

　　exercise.

　　"The potential for Divine Strake to create health and safety impacts to the

　　general public is minimized by a combination of the remote location of the NTS，

　　the sparse surrounding population， and a comprehensive program of

　　administrative and design controls，" the agency said.

　　环球在线消息：美国国防部一名高级官员透露，美军计划进行代号为“神圣列板”（Divine Strake）的试验，将引爆当量相当于700吨炸药的武器，爆炸后的蘑菇云将覆盖内华达州城市拉斯维加斯上空。

　　据法新社3月30日报道，美国国防威胁降低局（Defense Threat Reduction Agency）局长詹姆斯·特内利亚说：“我不想听上去显得油嘴滑舌，但这将是自从我们停止试验核武器以来，第一次在拉斯维加斯上空看到蘑菇云。”

　　特内利亚还说，美军正在开发能够摧毁地下掩体的武器，而这个试验就是这种武器开发的一部分。他指出：“我们正在开发大型的穿透器，包括将在内华达州试验的当量相当于700吨炸药的武器，以便在常规武器范围内达到最大的威力。”此次试验的目的是检验爆炸对花岗岩建筑的破坏程度。

　　特内利亚表示，美方已经通告俄罗斯，将于在今年6月的第一周内在内华达州的试验场地进行试验。此外，他指出：“希望拉斯维加斯市民也能够理解。” （凌晨）
