首次提出激光辐照下双层金属板界面会由于变形而产生脱离 ,从而对双层板之间的传热有明显的影响 ,通过实验和数值模拟验证这一提法。该工作丰富了接触热阻概念 ,有助于进一步加深对强激光破坏机理的研究 ,同时提供了一条有效的抗强激光加固的途径 It is proposed for the first time that the interface of the double-layer metal plate under laser irradiation will be detached due to the deformation, which has obvious influence on the heat transfer between the two plates. Experiments and numerical simulations verify this reference. This work enriched the concept of contact thermal resistance, which helps to further deepen the research on the mechanism of strong laser damage and at the same time provides an effective anti-laser strengthening approach
