具有褶皱表面的磁性多层膜中线性及非线性表面静磁波

In these formulae,γ is the gyromagnetic ratio,and f1and f2 are used as the magnetic andnonmagnetic fractions in the multilayers,respectively.Therefore f1=d1/ ( d1+d2 ) and f2 =d2 / ( d1+d2 ) ,with d1representing the thickness of magnetic layers and d2 the thickness of nonmagneticlayers.In our previous paper[2 3 ] ,we obtained the useful non-zero components of the third-ordermagnetizations with foundation al frequencyω,for a surface magnetostatic wave propagatingalong the x axis,which arwhere…     

在固体基质表面制备具有催化活性的含酶分子多层膜

在固体基质表面自组装一层功能分子层,通过静电相互作用,将辣根过氧化物酶（ＨＲＰ）与双吡啶盐（ＰｙＣ６ＢＰＣ６Ｐｙ）交替沉积,制得多层酶电极。用紫外可见光谱法跟踪石英基片上的组装过程,详细描述多层膜电极以亚甲绿（ＭＧＨ）为电子中继体的电化学行为,并研究此传感器对过氧化氢的电催化还原反应。
