冲击波超压与动压
[解释]：　　核爆炸产生的高温、高压火球膨胀，在周围介质中形成连续向外传播的压力脉冲（或冲击波），冲击波阵面传播到空间某点时，超过周围环境大器的压力称超压；空气粒子高速随波阵面运动产生的冲击压力称动压。超压和动压都以帕斯卡（Ｐａ）为主单位。超压随时间的变化取决于爆炸威力、距爆点的距离和爆心周围的介质情况。特定地点的峰值超压一般出现在冲击波阵面到达该点的瞬间，超压在该点的持续时间称为正压作用时间。尔后，该点的压力下降到低于周围压力，称为负压，再逐渐回升到周围压力值。对人员的直接冲击伤，超压为２０—２９千帕可引器轻度伤；２９—５９千帕可导致中度伤；５９—９８千帕可造成重度伤；大于９８千帕可造成极重度伤。动压为１０—２０千帕可造成中度伤；２０—３９千帕可造成重度伤；大于３９千帕可造成极重度伤。动压的推动、抛掷和超压的挤压会造成物体变形和毁坏。
