这张鬼异的照片并不像光学照相机那样，它并没有显示光线照到空间站表面时的反射。事实上，雷达偏转波束根本没法侦测到空间站的外表。

This ghostly image does not show light reflecting from the surfaces of the space station like an optical photograph.

本文提出以双聚焦、无空间色散的设计原则，来代替常用的全消色差设计原则，使医用电子直线加速器的偏转磁铁能够具有更好的特性。

A double focusing, non spatial dispersion magnet design has been suggested to substitute the achromatic principle for improving the beam characteristics on target of the medical accelerator.
