爆

• There may also be an increase in the velocity of air particles in the blast wave due to precursor action .
  由于前驱波的作用，爆震波中的空气粒子速度可能增加。
• Ideally, a structure which is to suffer little damage from blast should have as much ductility as possible .
  按理想来说，结构的延性愈大则愈不容易为爆震波所毁。
• This figure shows four stages in the outward motion of the spherical blast originating from an air burst .
  图中表明空中爆炸时发生的球形爆震波向外移动的四个阶段。
• The transformer substation survived the blast with relatively minor damage to the essential components .
  经爆震波袭击后未被毁坏的变电站的重要组件受到较小的损坏。
• The blast wind has then effectively ceased and the direct destructive action of the air blast is over .
  爆震风已有效地停止了，于是空中爆震波的直接破坏作用就完结了。
• The shock wave is similar in general form to the blast wave in air, although it differs in detail .
  这种冲击波的一般形式与空中爆震波相似，然而在细节方面却又不相同。
• This first will be due to the incident blast wave and the second, a short time later, to the reflected wave .
  第一个是由入射爆震波引起的，第二个是稍晚产生的反射波。
• These variations are determined primarily by the type and extent of the surface over which the blast wave passes .
  这些变化主要决定于爆震波所通过的表面的类型和范围。
• This reflected blast wave, like the original (or direct) wave, is also capable of causing material damage .
  反射爆震波像入射（或直达）波）一样，也会对物质起破坏作用。
• Somewhat related to the condition of the surface are the effects of objects and material picked up by the blast wave .
  被爆震波掀起的物体和材料的效应与表面条件有些关系。
