This in turn left its mark on the polarization of the next photon, so amplifying the signal.

光子就这样轮流地将它的偏振标记留给下一个光子，因而增强了信号。

Because the image of backscattered electron could reveal structure of the mark as well as the surface, we chose the backscattered electron signal to detect the position of the mark.

由于背散射电子信号的图像既可以显示样品的形貌也可以显示样品的成分所以选择背散射电子信号进行标记位置检测。

A form of frequency modulation in which the carrier frequency is shifted between a mark frequency and a space frequency in response to the impressed intelligence signal (frequency-shift keying).

频率调制的一种方式，其中载波频率在标志频率和场频率之间移动，以响应外加的情报(数据)信号。

On the same date that the dual moving averages shows a very clear buy signal, the ADX is falling at 18.64, having crossed above the 20 mark the previous week.
