中文摘要：

Microreaction 技术是在化学工程，合成和过程技术的最创新、快速的发展中的地之一。向提高的产品选择，产量和纯净，改进安全，和新产品和过程的存取的许多期望被指导到 microreaction 技术。Microfluidic 混合器是在 microfluidic 设备的最重要的部件。基于各种各样的原则，活跃、被动的 micromixers 被设计了并且调查。这评论在 microfluidic 混合器集中于最近的开发。在活跃、被动的 micromixers 的流动现象和混合特征的概述被给出，包括在 micromixers 的物理现象和他们的利用的类型。由于在一个复杂 microfluidic 系统的简单制造技术和容易的实现， T-micromixer 作为一个例子被加亮在在 microfluidic 混合器内混合效率和液体流动上说明设计和操作参数的效果。

英文摘要：

Microreaction technology is one of the most innovative and rapid developing fields in chemical engineering, synthesis and process technology. Many expectations toward enhanced product selectivity, yield and purity, improved safety, and access to new products and processes are directed to the microreaction technology. Microfluidic mixer is the most important component in microfluidic devices. Based on various principles, active and passive micromixers have been designed and investigated. This review is focused on the recent developments in microfluidic mixers. An overview of the flow phenomena and mixing characteristics in active and passive micromixers is presented, including the types of physical phenomena and their utilization in micromixers. Due to the simple fabrication technology and the easy implementation in a complex microfluidic system, T-micromixer is highlighted as an example to illustrate the effect of design and operating parameters on mixing efficiency and fuid flow inside microfluidic mixers.
