The measure formula of the underwater explosion energy of the centralized charge and the linear charge is introduced in this paper;the quartz press electricity sensor was used to measure the underwater explosion shock wave parameter and the bubble wave parameter of the two kinds of charges in case of 0.25≤W 1/3 /R≤0.45 in centralized charge and 0.116≤W 1/2 /R≤ 0.509 in linear charge(W 1/3 /R was defined as the contrasting distance); And the least square method was used to regress the measurement datum;The relationship between the pressure of the shock wave interface, the general energy in the explosion of the two kinds of charges and the contrasting distance was concluded. The result indicates that the attenuation of the pressure in the shock wave interface of the linear charge is more slowly than that of the centralized charge, and the action time of the shock wave in the linear charge is longer than that in the centralized charge. The specific impact energy of the specific bubble wave energy in the underwater explosion of both kinds of charges is same, and the specific impact energy of the linear charge is higher by 17% than that of the centralized charge.
