在增益和噪声特性方面，后向抽运方式优于前向抽运方式。

The performance of the backward pumping is better than that of forward pumping in gain and noise features.

因为放大器的增益也可用耦合系数和规一化负电导来表示，因此在增益和有效噪声间获得一个单值关系式。

The gain of the amplifier is also given in terms of the coupling factor and the normalized negative conductance, the relationship between the gain and the effective noise figure is thus found.

在增益色散效应的影响下，得到自相似脉冲渐进解析解的振幅函数、相位函数、线性啁啾函数和脉冲时域宽度。

We have obtained the self-similar pulse amplitude function, phase function, strict linear chirp function, and thee?ective temporal pulse width.

That in many cases, I can gain efficiency if I'm willing to give up space. Having said that though, there may still be a problem, or there ought to be a problem that may be bugging you slightly, which is how do I guarantee that my hash function takes any input into exactly one spot in the storage space?

普遍存在的增益和权衡,在许多的例子中,可以通过牺牲空间而得到效率方面的增加,话说回来，仍然存在一个问题,或者应该会有一个问题困扰着你,就是我如何保证我的哈希函数能够准确将,任一输入映射到相应的唯一的存贮空间中去？
