Since that time, much more powerful weapons, with energy yields in the megaton range, have been developed

从那以后，已经制造出威力大得多的武器，产生的能量在兆吨级。

Titan I missiles (used 1962-65), designed to deliver a four-megaton nuclear warhead over 5,000 mi (8,000 km)to targets in the former Soviet Union, were stored in underground silos but had to be raised to ground level and fueled for launch.

泰坦1号飞弹(1926～1965年使用)，设计用来投射四百万吨级核子弹头，射程超过8000公里，对准前苏联的目标，储存在地下发射井中，在发射时上升到地面。

By 1965 they had been replaced by the much larger Titan II, which could be launched directly from its silo. With a nine-megaton warhead, Titan II was the principal weapon in the land-based U.S. nuclear arsenal until the 1980s, when it was replaced by solid-fueled ICBMs (e.g., Minuteman missiles).

在1965年由更大型的泰坦2号取代，此型可由发射井直接发射，带有九百万吨级弹头，一直是美国陆基核武的主要武器，到80年代被更精确的固体燃料洲际弹道飞弹(如义勇兵飞弹)取代。

||1:Supposedly the 20-megaton nuke of swear words, still considered by some people unacceptable at any time, the C-word does not pack the blast it once did.||2:Samantha Bee, an American comedian, used it on her news show to refer to Ivanka Trump, the president’s daughter, inciting only a short-lived controversy.||3:Numerous British television presenters have mistakenly substituted it, on air, for the surname of Jeremy Hunt, who was for a time culture secretary.||4:(Anticipating the “c” in “culture” may have been responsible for early slips of this type, but they mysteriously continued after Mr Hunt became health secretary.||5:) None of the presenters has been disciplined.

||1:据说2000万吨级的脏话核武器，仍然被一些人认为在任何时候都是不可接受的，这个C字母打头的词已经不像从前那样有震撼力了。||2:美国喜剧演员萨曼莎·比在她的新闻节目中用这个C字母打头的词来指代总统的女儿伊万卡·特朗普，这只引发了一场短暂的争议。||3:许多英国电视节目主持人在直播时错误地用它代替了杰里米·亨特（Hunt）的姓氏，亨特曾是《时代》杂志的文化部长。||4:(预料到“文化culture”中的“c”可能是造成早期这类口误的原因，但在亨特先生成为卫生部长后，这些口误神秘地继续着。||5:)这样说的人都没有受过训练。

At 1 mile from a 1-megaton explosion, for example, the duration of the positive phase of the blast wave is about 2 seconds.

例如在离一枚一百万吨爆炸一哩的地方，爆震波的正延续时间约为2秒。

Thousands of chunks of material from the comet would have rained down on Earth, each one releasing the energy of a one megaton nuclear bomb.

无数的大块彗星碎片雨点般落到地球上，每一个大块碎片的撞击都释放了一个百万吨级核弹所释放的能量。

Within a millisecond after detonation, the diameter of the fireball from a 1 megaton (Mt) air burst is 150 m.

在引爆后的几微秒之内，在百万吨空气冲击力下形成的火球直径将达150米。
