研究了外电场对光滑平板和抛光钢球之间纳米间隙内液膜的影响。研究发现，在赫兹中心区的边缘附近出现一些微气泡，然后离开中心区。实验结果表明，气泡的产生在很大程度上取决于液体的极性和外电压。据认为，气泡的出现是由于液体表面的振动。
The effects of an external electric field on liquid films confined within a nanogap between a smooth plate and a highly polished steel ball have been investigated. It was found that some gas microbubbles emerged around the edge of the Hertz central region and then moved off the central region. Experimental results indicated that the emergence of the bubbles was largely dependent on the liquid polarity and the external voltage. It is thought that the emergence of the bubbles is due to the liquid surface vibration.
