At last micro bubble generator with two heaters is experimentally studied with the purpose to apply it into thermal jet printer and eliminating satellite droplets. Interfusion and drive matching of two bubbles is realized in open liquid environment. 为了将器件应用于热喷印并消除次液滴现象,我们还对双加热器结构的微气泡发生器进行了实验研究,在开放的液体环境下实现了双气泡的融合与驱动的匹配。
