From this, a new research system-delivery of foreign DNA into microorganism via ion beam - was established, offering a new way to construct genetically engineered microorganism.
由此建立起离子注入介导微生物外源dna转导的研究体系，为微生物转基因工程提供了一条新的途径。

Ion implantation may echo on plant cell, thus provide convenicence for foreign genetic material transferring into cell.
低能离子束注入对细胞的刻蚀作用提供了外源遗传物质进入细胞的途径。

The method is not influence for sodium ion in sample, and not polluted by internal and foreign matter. And it has high specificity, precise testing result, and good accuracy.
