The results show that a sound bonded interface is obtained without sheet inclusion, pore and unbinding. The microstructure consists of bulk α-Mg phase and needle compound in the weld metal, element Al diffuses along the grain boundary of the substrate into the welding line. A little Y diffuses into the base metal. A little Mn and Cu segregate and element Ni distributes homogeneously and no segregation appears in weld area.

The second part was to test the appearance, ingredient analysis, surface potential, thermal conduction properties, and magnetism of the nano composite fluid prepared from the parameters. The experiment found that unoxidized particles, Ag, Cu, Fe, and Ni appeared round. If combined with oxygen in water as oxides, the nano particles would grow toward certain directions. In copper/iron nano composite fluid, FeO appeared cubic, Cu2O appeared coniferous. In silver/iron nano composite fluid, FeO was polygonal. In dielectric potential detection, the nano composite fluid was likely to aggregate and deposit, except for silver/iron set. In other sets, the pH of silver/cobalt nano composite fluid was 7, surface potential was 21.21mV; the pH for silver/nickel nano composite fluid was 6.5, surface potential was 21.04mV; the pH for copper/iron nano composite fluid was 7, surface potential was -30mV. The fluid particles of the three sets could all maintain suspension of 2 weeks or more. For thermal conduction, the silver/nickel, nano composite fluid showed the best thermal conduction. Under temperature of 30℃ fluid weight conduction of 0.4%, the thermal conduction increase was 26%. For magnetic detection, except for silver/iron nano composite fluid, the nano particles of other three sets were paramagnetic, and all four sets were soft magnetic nano composite materials.

第二部分。将由较佳制备参数所产出的奈米复合流体，进行形貌外观、成分分析、表面电位及热传导性质实验与磁性检测；在奈米颗粒的形貌部分，经实验发现Ag、Cu、Fe、Ni等未氧化的颗粒皆呈现近似圆形，而若与水中的氧结合形成氧化物，奈米颗粒则会朝特定方向成长，在铜/铁奈米复合流体中FeO为四方体结构、Cu2O的颗粒是针叶状，在银/铁奈米复合流体中FeO则为多边形结构；而介面电位检测方面，结果显示经本制程所产出的奈米复合流体除银/铁奈米复合流体这一组较容易聚集沉淀外，其他三组中银/钴奈米复合流体的pH值为7，表面电位为21.21mV，银/镍奈米复合流体的pH值6.5表面电位为21.04mV而铜/铁奈米复合流体的pH值为7时表面电位约在-30mV，且此三组流体颗粒皆能维持悬浮性2周以上，悬浮性较佳；热传导实验部分，四组奈米复合流体中以银/镍奈米复合流体在增进热传上效果最佳，在温度30℃及流体重量浓度0.4﹪条件下热传导系数增进达26﹪；磁检测方面，除了银/铁奈米复合流体外，其他三组奈米颗粒皆属顺磁性，且这四组奈米复合材料都是属软磁性。

Compared of the efficiency of treating heavy metals in FGD wastewater with NaOH, Ca_2 and Mg_2. It indicated that NaOH was much efficient for precipitated waste water; Ca_2 was much efficient for unprecipitated waste water, the removal efficiency reached 98.4%. With the increasing of the main ion of Ca~2+, Cl~- in FGD wastewater, the efficiency decreased. It decreased 60% for the removing of Mn and 10% for Zn, Cd and Ni. The rectification coefficient token the Ksp of practical wastewater because it quite different with theoretic Ksp at different pH; the theoretic and practice addition were proportioned and it commonly reached 1:300.The precipitation efficiency of Na2S at different pH and the effect of Ca2+ was determined.
