惊人科学新发现:二次大战削弱地球大气层_最新英语新闻

The bombs used by Allied forces during World War II were so large, they weakened the Earth’s upper atmosphere.

第二次世界大战期间,盟军使用的炸弹之大甚至削弱了地球的上层大气。

The air raids turned towns to rubble and ash, but now new research shows shockwaves could be felt up to 1,000 km above the UK.

空袭把城镇变成了废墟和灰烬,最新数据表明,当时盟军的炸弹爆炸冲击波可以在英国上空1000公里的空间感受到。。

Chris Scott, from the University of Reading said: "I was absolutely astonished [when I found out].

雷丁大学的克里斯·斯科特说:"当我发现这种情况时,我感到震惊。"

Each raid released the energy of at least 300 lightning strikes.

“当时盟军的每次大轰炸都释放出至少300次雷击的能量。”

It’s now hoped the research will give us a better understanding of how natural forces such as lightning, volcanic eruptions and earthquakes can affect Earth’s upper atmosphere.

现在,我们希望这项研究能让我们更好地了解闪电、火山爆发和地震等自然力量如何影响地球的高层大气。

Researchers studied daily records kept at the Radio Research Centre in Slough, UK.

研究人员研究了英国斯劳的无线电研究中心的每日记录。

They looked at how the concentration of electrons changed in the upper atmosphere around the time of 152 Allied air raids in Europe - including raids on Berlin and those in support of the Normandy landings.

他们分析了在二战中同盟国空军对欧洲大陆发动的152次大规模空袭时的大气电离层里的电子聚集浓度,这些空袭包括掩护盟军诺曼底登陆期间对柏林等德国地区的大轰炸。

The data showed the concentration of electrons fell significantly when a bomb was detonated, which in turn heated the upper atmosphere.

对有关数据分析的结果显示,当时一颗大型炸弹爆炸时,大气中电离层电子的浓度显著下降,从而也加热了高层大气。

This caused a small but significant depletion in the ionosphere above Slough, even though the bombs were deployed hundreds of miles away.

尽管炸弹区域位于数百英里(上千公里)之外,但这导致英国斯劳上空的电离层电子浓度发生了少量但明显的下降。

But Chris Scott admits "these were very temporary effects which heated the atmosphere very slightly."

但克里斯.斯科特承认,“这些都是非常短暂的影响,使大气温度略微升温。”

The effects on the ionosphere would only have lasted until the heat dissipated.

但斯科特也承认"这些都是非常暂时的影响,它们会使大气略微加热。"

Why do we need to know about the ionosphere?

为什么我们需要了解电离层?

It is a layer of the Earth’s atmosphere which can affect radio communications, GPS systems, radio telescopes and even some understanding of weather systems.

电离层是地球大气层的一层,它可以影响无线电通讯、GPS系统、射电望远镜,甚至还能影响天气系统。

Chris Scott said: "This [research] is really important if we’re going to understand the ionosphere as a whole.

克里斯斯科特说:“如果我们要了解整个电离层,这项研究就非常重要。

We know the ionosphere is controlled by solar activity but it varies much more than can currently be explained.

“我们知道电离层是由太阳活动控制的,但目前其多样化的变化却远超过我们目前能解释的部分现象。”
