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-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.
Based on the large-scale Asay-F window design, the information on the mass and density-velocity distribution of microparticles on the surface of metal Pb samples under different loading conditions was accurately diagnosed. The similarities and differences of the micro-spray characteristics on the surface of metal samples before and after melting were explained. The physical reason for this phenomenon was explained from the theoretical analysis. It laid an important foundation for studying the mechanism of the influence of the melt on the surface of the metal micro-jet.
