With these equations, they have investigated the problem of Faraday rotation in a longitudinally magnetized ferriterod with tapering cross-sections at both ends.
利用这组方程，作者研究了纵向磁化铁氧体柱中的法拉第旋转（铁氧体柱的两端是截面变化的圆锥）。

The degenerate ferrite consists of rod-like subunits, each several micron in length and 1-2 micron in diameter.
