On the purpose of catching up with the advanced level of the world , and developing microinjection devices of ourselves to promote the chinese gene engineering , this paper is dedicated to the design and fabrication of the microinjection volume controller and the research on the detection of microinjection volume by micro - vision , based on looking into the advanced products mentioned above and researches on the dynamical characteristics of the dna micro - fluid from both theoretical and experimental aspects 为了追赶世界先进水平，同时也为了开发具有中国特色的显微注射设备，以推动我国基因工程的发展，本论文在深入调查了解国外先进产品，以及从理论及实验方面对dna微流体的动力学特性进行研究的基础上，致力于微注射量控制器的设计与研制，以及显微视觉检测技术的研究，以便对其进行更有效、更精确的定量控制。
And so , we developed a leec biochip and a control system for it . my dissertation includes theoretical design of linear - arrayed electrodes and , the procedure of microfabricating microfluidic channel by using an elastomeric materials - pdms . as a result , different type of pdms - glass leec chip was designed and produced 近年研究表明，在生物芯片上集成特定结构的电极阵列，用电学方法可以精确操控微流体及生物分子的行为，本论文从生化分析的电控机理出发，研制了leec芯片及其控制系统。
Low frequency micro - vibration causes the micro - fluid to produce uniform dispersion and injection which carried out a hydrophobization treatment on the inner wall of micro - nozzle , thus eliminated the spontaneous flowing of micro - fluid inside the micro - nozzle due to wet ting effect so as to let the micro - injection be provided with a digitalized and volume controllable character 压电陶瓷低频微振动使得微流体产生均匀的离散和喷射；对微喷嘴内壁进行疏水化处理，从而消除微流体由于湿润作用在微喷嘴内部的自发性流动，使得微喷射具有数字化量可控的特征。
Several research works are done in this paper according to the topics mentioned above : 1 . looking up a lot of documents and materials about the microinjection technique , devices and the controlling technology of micro - fluid from outside and inside the country . based on the theoretical researches about the dna micro - fluid ' s dynamical characteristics , the controlling model of the microinjection volume is set up , and the experimental research on it is also done 围绕上述内容，本文进行了以下几方面的研究工作： ( 1 )查阅并分析了国内外大量的转基因微注射技术及操作设备和微流体控制方面的文献，在对dna微流体的动力学特性理论研究的基础上，进行了微注射量的理论建模及实验研究。
