That makes sense, though, because margin and capacity are relational concepts: margin is the difference between your total capacity and how much of that capacity you're using.

尽管如此，让我试着这样说，余地和最大能力是两个相关的概念：余地是你能发挥的最大能力和你所实际运用的能力之间的差额。

In the meantime, the reserve margin—the excess of generation capacity overpeak demand—has shrunk to about 8%, compared with the international standard ofat least 15%.

同时，电源储备量——超过峰值需量的额外发电容量——已减少了8％，而国际标准是至少15％。

Meanwhile, the shortage of capacity means that its margin of excess power has been shrinking for 20 years.

而且，生产力短缺意味着过剩电量在二十年来在不断减少。

Meanwhile, the shortage of capacity means that its margin of excess power has been shrinking for 20 years.

同时，产量的缺少也意味着20年来其过量能量的边际效应一直在缩小。

Then you will know how much safety margin you have and when you need to ramp up capacity for your super-popular applications.

于是，您将知道您的安全幅度有多大以及什么时候需要为非常流行的应用程序进行扩容。
