中国科学家用声波悬浮动物

by zqyin on 12月 9, 2006

据《自然》以及《科学时报》报道,西北工业大学的科学家在试验中用声波将鱼、蚂蚁等活着的小动物悬浮起来,而且不对它们造成明显的伤害。这项技术可以用来研究和制备新材料,也可能用于广告:“当你将一只青蛙或一个草莓漂在空中,你就能感觉到这件事情带来的爆炸性影响。”Christianen说。这个工作发表在《应用物理快报》上:Appl. Phys. Lett. 89, 214102 (2006)

It seems like they take advantage of the second order term of the sound pressure, which is called acoustic pressure. And its intensity is ~10 Pa

这么小?看来人是不可能被声音支持飘起来的了。
