摘要：介绍了微流体脉冲驱动一控制技术，分析了微流体脉冲驱动一控制过程，指出在这一过程中影响微流体流动的主要因素是微流道固壁加速度和流体内部的黏性力。采用”椭圆修圆法”对方波驱动电压进行修圆，针对修圆点的位置决定微流体的驱动方向，获得了不同修圆位置和修圆系数的驱动电压修圆波形。通过实验探索了波形修圆对微流道固壁运动加速度、微流体脉冲惯性力和流体驱动效果的影响规律并进行了机理分析。所得流体体积流量可在0～15．4pl／min连续变化，远小于现有的微流体驱动技术。本文的研究成果可为微流体脉冲驱动一控制技术在微流体系统中的进一步应用提供参考。

Abstract： Pulse driving and controlling technology of micro-fluids was introduced. The pulse driving and controlling process of micro-fluids was analyzed in detail and it points out that the acceleration of micro channel solid wall and the viscosity force of micro-fluidic are the main factors that influence on the flow of the micro-fluids. A method of ＂ elliptic rounding＂ was adopted to round driving voltage waves. As the driving directions of the micro-fluids were determined by the locations of rounding points, a series of waves with different rounding locations and rounding coefficients were obtained. The influence rules of rounded waves on the acceleration of micro channel solid wall, micro-fluidic pulse inertial force and driving effects were researched by experiments. The experimental result indicates that the flow rate of micro fluidic volume can be in the range of 0-15.4 pl/min, which is more better than that of the current micro driving technology. The research results can provide a reference for the research on the further application of pulse driving and controlling technology of micro-fluids in micro-fluidic systems.
