爆炸产生的焊缝的一个特殊特征是焊接界面的轮廓通常具有规则的波状外观。在过去的十年中，一些作者假设了这些波的产生机制，并试图将他们的理论预测与可用的实验数据联系起来。然而，到目前为止，对于实际上造成波浪的特定机制还没有达成共识，而且实际上提到的几种机制是相互矛盾的。在简要讨论了一些已提出的理论后，对其中之一，即 Kowalick 和 Hay5 最近描述的涡旋脱落机制进行了更详细的研究。给出了涡流脱落替代参考文献中使用的一些理论和观察的说明。 （5）试图确定一个可能最终对产生界面波的机制进行定量和定性准确描述的区域。
A particular characteristic of an explosively produced weld is that the profile of the weld interface often has a regular wavy appearance. During the last decade several authors have postulated mechanisms by which these waves are produced and have attempted to correlate their theoretical predictions with available experimental data. As yet, however, there is no consensus of opinion on the particular mechanism which is actually responsible for the waves and indeed several of the mechanisms referred to are mutually contradictory. After discussing briefly some of the theories which have been proposed, one of them, the vortex shedding mechanism recently described by Kowalick and Hay5, is examined in more detail. An account is given of some theories and observations of vortex shedding alternative to those used in ref. (5) in an attempt to identify an area which might eventually lead to both a quantitatively and qualitatively accurate description of the mechanism producing the interface waves.
