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）。
With these equations, they have investigated the problem of Faraday rotation in a longitudinally magnetized ferrite rod with tapering cross-sections at both ends.
但是不要要求对他的优雅证明的解释，除非你对圆锥截面感兴趣。
But don't ask for an explanation of his elegant proof unless you are interested in conic sections.
圆锥楔形体的结构至少有四个圆锥面组成，在每个面上，可以使用相同的横截面，也可用不同的横截面。
Their conical sphenoid part, for the configuration of which at least four conical surfaces are used, can have the same cross section all over its length or different cross-section per parts.
结果表明：在强激光冲击下，试样发生显著的塑性变形，变形后轴截面形状为类圆锥形；
The specimen irradiated by intense laser generates distinct plastic deformation, and the profile of axial cross section of specimen after shocking is similar to a coniform figure.
