利用点接触反射方法获得可靠的自旋极化信息还有赖于接触界面特征的进一步分析。而一个更切合实际的、更完善的理论成为迫切的需要。
Further analysis of the contact interface and a more complete theory are needed to extract a reliable spin polarization message with the point contact Andreev reflection method.
雷达信号接触到飞机的任何部位，都会有部分被反射回来。
No matter where the radar signal hits the plane, some of the signal gets reflected back.
要是您有机会接触下那种可以从天花板或者墙壁反射回来的闪光灯，效果则会明显得多。
If you have access to a flash that can bounce off the ceiling or walls, that could work much better.
