| 摘 要： | 通过对两类超细铁粉的试验研究和理论分析，对其微波吸收性能进行了探索，指出超细铁粉存在自由电子吸波与磁损耗两种机制。研究结果还表明：超细铁粉的形貌、微观结构、粒径及其分布与超细铁粉在粘结剂中的分散状态对其微波电磁性能产生一定的影响。

| Abstract: | In this paper ,microwave absorbing properties of two kinds of ultrafine Fe particles were investigatedby theoretical analyses and experimental works, The radar absorbing mechanism for ultrafine Fe particlesmay be stated as free electron ohmic heating and magnetic energy losses. The results also show that charac-teristics of ultrafine Fe particles,such as shapes,microstructures,sizes and size-distributions and scatteringstates in the binders,have great influence on their microwave electromagnetic properties. |
