In the United States, domestic weapons recycling programs are smaller in scale and would be no replacement for Megatons for Megawatts.

在美国，国内武器回收方案规模上小一点而且没有《百万吨核弹换百万瓦核电》的替代品。

In the event, it may have yielded 57 megatons - which would have made it just under four times as destructive as the Tunguska meteorite.

这次爆炸事件中，可能产生了5700万吨的爆炸力——使它所造成的破坏力大概仅次于通古斯流星爆炸的四倍。

The blast, which has been estimated at the equivalent of around 15 megatons of TNT is widely thought to have been caused by a meteor a few tens of metres across exploding in mid-air.

这次爆炸，其爆炸能量估计相当于约1500万吨的TNT，广泛认为是由跨度为数十米的一颗流星在半空中爆炸所造成的。

By analyzing the white pumice for geochemical clues, the team found that the Millennium Eruption actually emitted a large amount of sulfur into the atmosphere: an estimated 45 megatons.

通过分析白色浮石的地球化学线索，研究小组发现，“千年大喷发”实际上向大气中排放了大量的硫：大约45兆吨。

Why do we persist in the same contradictory behavior day after day, century after century, alternating between Chartres and the Crusades, between grief and gore, between moonwalks and megatons?

为什么我们日复一日，一个世纪又一个世纪地坚持同样矛盾的行为？
