Re also enhanced the deposition potential , polarizability and cathode overpotential of the baths , changed the result of chemical deposition reactions and actuate the deposit of cobalt alloy . and the chemical deposit co - b - re , co - ni - p - re alloy include re which electrode potential is much more negative was obtained . the structure of co - b - re was composed of microcrystal Re还提高了镀液的静止析出电位、极化度和阴极过电位，改变了化学沉积反应的强弱次序，加强了钴基合金的析出反应，成功地获得了含电极电位较负的re ( la , ce , y )的化学沉积co - b 、 co - ni - p薄膜。
Conclusion : we have obtained the prokaryotic reconbinant cloning and expression plasmid of pp - galnac - t2 successfully , which establish a foundation for further research . the expression of pp - galnac - t2 differs obviously in different tissues , showing the possible relationship between the expression of pp - galnac - t2 and the functions of tissues , which desires our further probing 结论本研究成功地获得pp - galnac - t2的原核重组克隆和表达质粒，为进一步研究打下基础； pp - galnac - t2在不同组织中表达的高低有较大差异，提示了它与组织功能的相关性，值得进一步研究。
