提出了一种进一步增强水下电线阵爆炸产生的固定能量激波的节能方法。基于圆柱形线阵的配置，方法是用<inline-formula> < text -math notation="LaTeX">$N$ </ text -math></inline-formula>较细的导线替换一根直径为0.2 mm的导线，同时保持这些<inline-formula> < text -math notation="LaTeX">$N$ </ text -math></inline-formula>导线的总质量等于该0.2 mm导线的质量。随着线数的增加，线阵轴线处的最大波压从1根直径0.2 mm的线的28 MPa增加到16根直径0.05 mm的线的90 MPa左右。单根线产生的激波正比于<inline-formula> < text -math notation="LaTeX">${1/}({N})^{1/2} $ </ text -math></inline-formula>而不是<inline-formula> < text -math notation="LaTeX">$1/N$ </ text -math></inline-formula>，这应该是增强的原因。讨论了来自每根单线的激波的相互作用。它可以大致分为两种，“非重叠”和“重叠”。“不重叠”只发生在不超过四条线的线阵中。在向线阵轴线传播的过程中，来自线阵的冲击波即使在接近轴线时也不会重叠。轴上的冲击波是所有导线上冲击波的总和。相反，“重叠”发生在不少于7根线的线阵中。即使远离地轴，电线发出的冲击波也会重叠。由于激波的会聚作用，轴向处的激波比来自所有导线的激波之和要低得多，特别是当导线数较多时。
An energy-efficient method for further enhancing the shock wave generated by underwater electrical wire-array explosion at a fixed energy was developed. Based on the configuration of a cylindrical wire-array, the method was to replace one wire of 0.2-mm diameter with <inline-formula> <tex-math notation="LaTeX">$N$ </tex-math></inline-formula> thinner wires, while the total mass of these <inline-formula> <tex-math notation="LaTeX">$N$ </tex-math></inline-formula> wires was kept equal to the mass of that 0.2-mm wire. As the number of wires increased, the maximum wave pressure at the axis of the wire-array increased from 28 MPa for 1 wire of 0.2-mm diameter to about 90 MPa for 16 wires of 0.05-mm diameter. The shock wave generated by one single wire was proportional to <inline-formula> <tex-math notation="LaTeX">${1/}({N})^{1/2} $ </tex-math></inline-formula> rather than <inline-formula> <tex-math notation="LaTeX">$1/N$ </tex-math></inline-formula>, which should be the reason for the enhancement. The interaction of shock waves from each single wire was discussed. It might be roughly divided into two kinds, “non-overlapping” and “overlapping.” The “non-overlapping” occurred only in the wire-array with not more than four wires. While propagating toward the axis of the wire-array, the shock waves from the wires did not overlap even when they were close to the axis. The shock wave at the axis is simply the summation of the shock waves from all wires. In contrast, the “overlapping” occurred in the wire-array with not less than seven wires. The shock waves from the wires overlapped even when they were far from the axis. Due to the converging effect of shock waves, the shock wave at the axis is considerably lower than the summation of shock waves from all wires, especially when the number of wires is larger.
