We can also see that because damping factor is a ratio that requires the load impedance to compute, it must be stated against some known impedance to be meaningful.

我们还可以看到因为阻尼因子是一个比率值，而且需要负载阻抗已知才能够进行计算，所以阻尼因子必须和某一已知的阻抗同时具明才有意义。

"But if damping factor is a number derived from the speaker impedance, and speaker impedance dances all over the chart, how can damping factor just be a single number?"...

"但是如果阻尼因子是从扬声器的阻抗计算出来的数值，而且扬声器阻抗会在整个图表上跳舞的话，怎么有可能阻尼因子只是一个单一的数字？"。。。

Technically, the damping factor is the specified load impedance (in use, that'd be the speaker system) divided by the amplifier's output impedance.

技术上，阻尼因子就是指定的负载阻抗（实践中，也就是扬声器系统）除以放大器的输出阻抗。
