Srtio _ 3 ( sto ) thin films exhibit a large electric field dependence of dielectric permittivity. the microwave surface resistance of yba2cu3o7 - x ( ybco ) is much lower than that of the normal conductor. the typical value of rs for ybco epitaxial thin film is smaller than 1 m
在低溫下， srtio _ 3 （簡寫為sto ）薄膜具有強烈的非線性介電性質，即:介電常數隨外加直流電場變化而變化; yba2cu3o7 - x （簡寫為ybco ）具有極低的微波表面電阻， rs （ 10ghz ， 77k ） < 1m ，而且它們的晶體結構相似，晶格常數匹配以及化學性質相容。 -
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:提出了用強脈沖磁場和電流細化金屬凝固組織的新工藝.與未經磁場或電流處理的凝固樣品相比，強脈沖電磁場能夠顯著地改善ly12鋁合金的凝固組織，使晶粒明顯細化、球化，電磁場的強度愈強，這種改善效果愈明顯.對該新工藝的細化機理進行了理論分析，同時，指出了實驗中的新現象和新問題
