The microstructure of longitudinal section in rebar was banded ferrite and pearlite and the ferriteband density reduced gradually along radius of rebar.
纵截面上，在铁素体基体上分布着沿轧向呈纤维状的珠光体，铁素体条带密度从边缘至芯部呈逐渐减少的趋势。

The developed theory is used to analyse the impedance-match problem of microstrip meander line ferrite phaser in X-Band, C-Band, and a good agreement with the experimental results is obtained.
用所得理论来分析X波段和C波段弯曲线型微带铁氧体移相器的阻抗匹配问题，与实验结果十分符合。
