Al中的空化气泡-10重量%采用同步辐射X射线成像技术对铜熔体进行了研究。现场观察发现，大部分气泡集中在辐射面附近的强烈空化区。测量的近最大气泡半径服从类似的截断高斯分布在水中，但增加了近一个数量级，由于在铝熔体中施加更高的超声强度。(C)2013爱思唯尔有限公司版权所有。
Cavitation bubbles in Al-10 wt.%Cu melt has been investigated by adopting synchrotron radiation X-ray imaging technology. In-situ observation reveals that most of bubbles concentrate within an intense cavitation zone nearby the radiation face. The measured near-maximum bubble radii obey a similar truncated Gaussian distribution as in water but increase by nearly the magnitude of one order due to higher ultrasonic intensity applied in aluminum melt.
