摘　　要：微混合通道是微流控芯片实现功能的重要结构。微丝模塑法制作的微流动混合圆通道,具有特殊"立体"结构的侧壁沟通式通孔。通过数值模拟方法,定性描述了沟通通孔处的流场特征,以此来辅助设计微混合通道,并初步探索了微流动混合圆通道的粒子合成能力。结果表明,微丝模塑法制作的微混合圆通道较相同条件下的软光刻通道具有更好的流场特征,并为粒子合成提供了一条新的途径。Micro-mixing channel plays an important role in microfluidics. Microcircular channel fabricated by microwire molding method features the exclusive wall-through hole. Velocity vectors at crossing hole were used to characterize the microflowing channel and aided design of micromixing channel. Synthesis of particles was primarily realized by the micromixing channel. The results showed that microciruclar channel, compared with microchannel fabricated via soft photolithography method, performed better in mixing two separate fluids and provided a novel way to synthesize particles.
