Dianci bileiqi, 2015 通过分析测试国内外氧化锌电阻片的电气性能结果及化学成分,发现电气性能优异的原因是在配方中未添加Cr2O3和SiO2成分,而添加了其他微量元素,从而改变了烧成后电阻片的微观结构。通过参考引证有关研究文献和专利,研发出的新型氧化锌电阻片配方的电气性能效果较好。

Fabrication and Investigation of the Fe-Ni Based Nanostructured Soft-magnetic Film for High-frequency Application [PDF]
, 2013 随着电子信息技术的飞速发展，电子元器件的工作频率和集成度不断提高，作为电子元器件关键组成部分之一的磁性元器件必然要向微型化、集成化、高频化方向发展。但是传统的铁氧体材料饱和磁化强度较低，受自身性质的限制不能在GHz频率范围具有较高的磁导率，因此不能满足当前电磁元件的需求。目前，具有高饱和磁化强度的软磁薄膜越来越受到重视，成为高频磁性材料研究的热点。为了使软磁薄膜能够具有好的高频特性，它不仅需要具有高的饱和磁化强度和高磁导率，而且需要具有较大的电阻率以及适当大的面内磁各向异性场 ...
