损耗性衰减;
The dissipative attenuation Mechanism of the Mn-Zn ferrite that involved the natural resonance, the piezoelectric resonance and the magnetic hysteresis loss are also studied.
本文还分析了锰锌铁氧体自然共振、磁滞损耗和畴壁共振等磁极化机制衰减吸收电磁波的各种机理。
The echoes of GPR ( Ground Penetrating Radar) are more and more dissipative attenuation with the increase of the depth of detection in GPR so that it is more difficult of deep detection at same time the decreased resolution.
探地雷达回波因为地下介质的损耗造成其随着深度的增加而衰减增大,导致对深埋目标探测更加困难,分辨率因此而降低。
