我们首次报道了在液体介质中产生的带电同轴射流的微米直径。给出了预测同轴射流内、外径的标度律。我们展示了一些实验，说明同轴射流的形成过程，并演示了这个过程如何可以用来产生微米尺寸的O/W（水包油）或O/W/O（油/水/油）乳液。还指出了与其他流体动力聚焦过程的一些有趣的类比。
We report for the first time the generation of electrified coaxial jets of micrometric diameter in liquid media. Scaling laws to predict the inner and outer diameter of the coaxial jet are given. We show some experiments illustrating the formation process of the coaxial jet, and demonstrate how this process can be used to yield either o/w (oil in water) or o/w/o (oil/water/oil) emulsions of micrometric size. Some interesting analogies with other hydrodynamic focusing processes are also pointed out.
