barium ferrite 中文意思是什麼
-
Research and application of barium ferrite thin films
鋇鐵氧體薄膜的研究及應用 -
The elements of ferrite magnet are ferricoxide barium strontium. ferrite has highter coercive force and highter resistance to bedemagnetized and oxidized than other non - rare earth permanent magnets. the biggest advantage of such magnet is their low cost. it is widely used from motors and loudspeakers to toys and craft etc.
鐵氧體由氧化鐵、鋇、鍶等元素組成，與其它非稀土磁鋼相比，鐵氧體的矯頑力和抗腐性都比較好，尤其它的低成本更是其它磁鋼所無法比擬的。它被廣泛應用於從電機、揚聲器到玩具、工藝品等各個領域 -
When the doping amount of these four rare earths is lower, coercive force of la and sm - doped barium ferrite powders shows a similar regularity, that is, there exists a minimum, whereas there exists a maximum in nd and gd - doped barium ferrite powders. when the doping amount is higher, coercive force increases greatly with the increasing of the doping amount
樣品的矯頑力在摻雜量較低的范圍內出現一個極值（ la和sm摻雜時為極小值， nd和gd摻雜時為極大值） ；在摻雜量較高的范圍內，矯頑力隨摻雜量的增加而大幅度增大。
