摘　　要：通过对行波及声流产生机理的研究,得出微管中的流体产生与行波同方向的声流。利用FPW(flexura lp late w ave)装置进行了跟踪、染色试验,验证了超声行波对微流体驱动的可行性。作为一种新型微流体驱动技术,行波微流体驱动能很好的弥补现有驱动和控制技术的不足。Acoustic streaming is a non- linear effect caused when sound wave spread in the fluid, Acoustic streaming was generated by the fluid particle vibration at a balance moving place when actuator vibrates. And without powerful sound wave,acoustic streaming can be formed when the frequency high enough. In this paper, Acoustic streaming was proved to generate in micro-fluid with the same direction of traveling wave through researching the generation mechanism of traveling wave and acoustic streaming, The feasibility was confirmed by tracing and dyeing tests using FPW, As a new technique of driving micro-fluid,it can supply a gap of the present micro-fluid driving techniques.
