refined metal meaning in Chinese

精炼金属

The ores arrive by ships from africa ; the refined metal is sent aloft to orbiters manned by igigi , then transferred to spaceships arriving periodically from nibiru
矿石通过船只从非洲运到这里，精制的金属制成的由高处而下的盘旋物是由伊吉吉驾驶，然后就周期性地转送到由尼比奴而来的太空船。
Abstract : it was studied by us that new technologies using strong pulsed magnetic field and electric current were applied to refine metal ' s solidified structure . these technologies improved remarkably the solidified structure of ly12 aluminum alloy and made the solidified grains more equiaxed and apparently finer compared with that of the normal sample , which is of more dendrite grains . the stronger the strength of the pulsed electromagnetic field , the better the improvement effect was . the refinement mechanisms of the new technologies were analyzed theoretically . new phenomena and problems occurred in our experiments were also pointed out in this paper
文摘:提出了用强脉冲磁场和电流细化金属凝固组织的新工艺.与未经磁场或电流处理的凝固样品相比，强脉冲电磁场能够显著地改善ly12铝合金的凝固组织，使晶粒明显细化、球化,电磁场的强度愈强，这种改善效果愈明显.对该新工艺的细化机理进行了理论分析，同时，指出了实验中的新现象和新问题
