如果伊娃能够截取鲍勃方发送的这两道脉冲，并改变其间距，就可以诱使爱丽丝方发送出与原计划略有不同的极性光子。

If Eve intercepts Bob's pulses and changes the separation between them, she can trick Alice into sending photons that have slightly different polarisations from those that were intended.

脉冲重复率越高，齿间距越大，各个齿之间也越容易分辨。

The faster the pulse repetition rate, the wider the spacing between the teeth, making each individual tooth easier to identify.
