  摘要：

  本研究涉及Li^{+、Mg2+、MoO_{4对3003铝合金在3% NaCl溶液中的腐蚀抑制作用2-、NO2- 和 CrO42- 离子。使用的方法是极化曲线的测定和表面状况的金相检查。结果表明，测试的离子对腐蚀过程有抑制作用。对这些离子效果的比较研究表明，在25至65°的温度范围内，Mg2+离子是最有效的离子C.抑制效率随着这些离子浓度的增加而增加，对于 5 × 10-2 合金达到最大值 86%。结果，点蚀电位和腐蚀电位之间的差距变得更大。在 75°C 时，Mg2+ 离子往往会刺激所考虑的氯化物溶液中 3003 合金的腐蚀。}}

  The present invention describes a synthetic non-viral vector composition for gene therapy and the use of such compositions for in vitro, ex vivo and/or in vivo transfer of genetic material. The invention proposes a pharmaceutical composition containing 1) a non-cationic amphiphilic molecule or macromolecule and its use for delivery of nucleic acids or 2) a cationic amphiphilic molecule or macromolecule that transforms from a cationic entity to an anionic, neutral, or zwitterionic entity by a chemical, photochemical, or biological reaction and its use for delivery of nucleic acids. Moreover this invention describes the use of these non-viral vector compositions in conjunction with a surface to mediate the delivery of nucleic acids. An additional embodiment is the formation of a hydrogel with these compositions and the use of this hydrogel for the delivery of genetic material. A further embodiment of this invention is the use of a change in ionic strength for the delivery of genetic material.
