数值计算已经进行了大约20年，其结果以矢量或格子表示的方式进行了图示。这些结果目前主要用于阐明超声与材料和缺陷相互作用的机理，以及检验和改进实验结果。这篇论文的一些部分回顾了结果，其中许多涉及不同几何形状的裂纹尖端衍射，这些结果主要发表在会议记录上，还没有出现在期刊上。其他部分，涉及各向异性介质中的聚焦场、焦透镜和辐射，都是新的，甚至还没有作为会议论文出现。
Numerical calculations have been carried out for about 20 years, and the results are demonstrated graphically by vector or lattice representations. These results are now being used mainly for clarifying the mechanisms of ultrasonic interaction with material and defects and checking and improving the experimental results. Parts of this paper review results, many involving cracktip diffraction in various geometries, which have been published mainly in conference proceedings and have not appeared in journals. Other parts, dealing with focused fields, focal lenses, and radiation in an anisotropic medium are new, and have not appeared even as conference papers.
