positive impulse

Methods The physical parameters of blast wave were measured by PCB pressure transducers ( USA) during underwater and air explosions of 200g, 500g and 1000g TNT respectively. Consequently, the propagation speed, peak overpressure value, positive duration and impulse of blast wave were analyzed.
