The main research works carried out in this paper are as follows : many literatures in the fields of transgenic technology, transgenic equipment and micro flow control technology are consulted and analyzed . according to the requirements of accuracy, repeating capability, agreeability, compatibility with environment and biology substance, a kind of electrical control microinjection system with gas nitrogen as injection pressure medium was chosen as desired 目前,关于这两方面的研究较少,因此本文围绕着转基因微注射系统中的超微量注射控制技术和立体显示技术进行了以下几方面的研究工作:根据转基因超微量注射操作作业的特殊要求,设计出气压电控式超微量注射控制器。
