The higher the initial relative peak power is, the higher the compression ratio and compressed peak power of the bright pulse are.

初始相对峰值功率愈高，亮脉冲的压缩比和压缩后的峰值功率愈高，同时所需的光纤长度愈短。

And if, on top of the bright pulse, a smaller pulse of just the right type is sent, the detector can be forced to record a one or a zero.

并且，如果在强脉冲之上，有一较小的，类型恰巧合适的脉冲发射的话，探测器就只能记录下一个1或者0。

The results show that the compression ratio and compressed peak power of the bright pulse depend upon the initial relative peak power of the dark pulse to the bright pulse.

结果表明，亮脉冲的压缩程度与暗孤子相对于亮脉冲的初始峰值功率有关。

And if, on top of the bright pulse, a smaller pulse of just the right type is sent, the detector can be forced to record a one or a zero.
