Ejecta on Pb surface below and above melting pressure

摘要: 利用设计的大量程Asay—F窗技术，从实验上准确诊断了不同加载状态下金属Pb样品表面微喷物质量和密度一速度分布信息，重点阐释了熔化前后金属样品表面微喷特性的异同，并从理论分析的角度解释了该现象产生的物理原因，为研究熔化对金属样品表面微喷射的影响机制奠定了重要基础．

Abstract: In this paper, Asay-F-window diagnostic technology for high density and large mass ejecta measurement is designed. By Asay- F-window technology, the mass and the density-velocity distribution of ejecta from Pb surface are presented. The difference in ejecta between below and above Pb melting pressure is particularly studied. Moreover, the physical causation inducing the ejecting difference is well explained through theory analysis.
