| 中文摘要: |
| 用高速摄影技术，在表面张力不同的四种液体中，对电火花放电造成的单空泡膨胀及收缩过程观测表明，含沙浓度对空泡的膨胀及收缩过程的影响类似于液体粘滞性对空泡的膨胀及收缩过程的影响. 文中分析了表面张力的影响程度。 |
| 英文摘要: |
| By using high-speed photography the authors investigate the effect of sediment concentration on the expansion and collapse process of single bubble generated by electric sparks in four fluids with different surface tension. Camera speed is 2×10^5 frames per second. The main conclusion is that the effect of sediment concentration is similar to that of fluid viscosity. |
