补充资料: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。
