研制了一种低驱动功率声表面波（SAW）雾化器。声表面波驱动结构由一个单向叉指换能器、一个喇叭和一个制作在128 degY × LiNbO 3基片上的波导组成。在约78 MHz的频率下，约1 W的驱动功率足以使水连续雾化。液滴的平均直径和雾化速率分别为约1.5 μ m和40穆尔/min
A low driving power surface acoustic wave (SAW) atomiser has been developed. An SAW driving structure consists of a unidirectional interdigital transducer, a horn, and a waveguide fabricated on a 128degYXLiNbO 3 substrate. At a frequency of about 78 MHz, about 1 W of driving power was sufficient for continuous atomisation of water. Mean diameter of droplets and atomising rate were about 1.5 mum and 40 mul/min, respectively
