摘要
依据绝热冲击波流体力学相容关系，采用高速摄像判读出冲击波波阵面的传播速度，进而计算出冲击波超压，并将其与实测超压及经验公式计算结果进行对比，验证了通过高速摄像测量波阵面运动速度的方法间接求得冲击波超压的可行性和准确性，为爆炸冲击波参数测量提供了一种十分有效的非直接测量方法。
According to the adiabatic shock fluid compatibility relations, the shock wave front propagation velocity is identified by high-speed camera, then the blast overpressure is calculated. The overpressure is compared with the measured overpressure and the calculated overpressure by empirical formula. The indirect measuring method by high-speed camera vides a very effecti to indirectly obtain blast overpressure is verified to be feasible and accurate. This method pro- ve indirect measuring method for measuring shock wave parameters.
