求翻译：一般来说，当微丝长度增加时，其轴向退磁因子Nz减小，这样就增大了玻璃包覆合金微丝的轴向磁各向异性，提高了共振频率，也增大了玻璃包覆合金微丝的磁导率虚部。共振频率的提高，则会降低其磁导率实部是什么意思？

In general, the when microfilaments length increases, its axial demagnetization factor nz decreases, thus increasing the glass-coated alloy microwires axial magnetic anisotropy, the resonance frequency, but also increased the glass package imaginary part of permeability cover alloy microwires. Reson

In general, when a population increases the length, the axial demagnetization factor Nz decrease, which would increase the size of a glass encased alloy micro-wire to the axis of the magnetic anisotropy, the resonance frequency, but also increase the size of a glass-encased alloy of permeability vir

In General, when Micro-Fiber length increases, the axial Nz demagnetization factor reduced, thus increasing the glass-coated alloy micro-filament of axial magnetic anisotropy, improving the resonance frequency, increase the permeability of the glass-coated alloy micro-imaginary part. Improvement of

Generally speaking, when micro silk length increase, its axial demagnetization factor Nz reduces, has like this increased the glass gable alloy micro silk axial magnetism aeolotropy, enhanced the resonance frequency, also has increased the glass gable alloy micro silk magnetic conductivity imaginary
