一、前言 x射线在材料中形成热击波,能导致材料层裂,这从实验室冲击波试验结果和核爆时回收的材料样品得到了征实。为了搞清楚它的破坏机理,国内外科学工作者从理论和实验方面做了大量的工作。理论上的计算模型,由于忽略的因素较多,计算模型预示的冲击波衰减率比实验中测得的低很多。这就迫使专家们更加注重实验技术和测试技术的发展,特别是使用敏感元件嵌埋于材 I. INTRODUCTION X-rays form thermal shock waves in the material that can cause splitting of the material, as evidenced by laboratory shock wave test results and material samples recovered during nuclear explosions. In order to clarify its mechanism of destruction, scientists at home and abroad have done a great deal of work in theory and experiment. Theoretical calculation model, due to neglected factors, the computational model predicts the shock wave attenuation rate is much lower than measured in the experiment. This forced the experts to pay more attention to the development of experimental technology and testing technology, especially the use of sensitive components embedded in wood
