A nuclear blast is an explosion with intense light and heat, a damaging pressure wave, and widespread radioactive material that can contaminate the air, water, and ground surfaces for miles around.

核爆炸会释放出高能量的光和热，破坏力巨大的压力波，而且四处飘散的放射性物质会污染数周围英里内的空气，水，和地表。

The main research. of this thesis is about the fireball 's temperature and the heat radiation effect of DEFAE (Double Event Fuel Air Explosion) and SEFAE (Single Event Fuel Air Explosion).

本文主要研究的是二次和一次引爆型燃料空气炸药(分别简称DEFAE和SEFAE)爆炸的火球温度及火球热幅射效应。

The relations between the maximum explosion pressure, the maximum quantity of draw-off heat and coal dust concentration, methane concentration were calculated.

分别推导出粉尘爆炸放热量和最大爆炸压力与煤尘浓度、甲烷浓度等影响因素的关系。

Many have cuts and broken bones from falling debris and burns from the intense heat of the explosion.

Theorists believe the rapid collapse generates heat that ignites the explosion.

An explosion is simply an exponential rise in heat.

Furthermore, it would take a combination of extreme events to make things dangerous in Tokyo (nuclear re-criticality, steam explosion) etc all of which are being rendered less and less likely as time passes and the heat decay process progresses.
