寿命

But now it is realized that supplies of some of them are limited, and it is even possible to give a reasonable estimate of their "expectation of life", the time it will take to exhaust all known sources and reserves of these materials.

但是现在人们意识到，他们的供应是有限的，甚至对它们的"寿命"进行合理估计都是不可能的，他们的寿命是指用尽所有的资源和储存的这些材料的时间。

The life curve of the transformer is different from life curve of the electronic product and it disobeys the exponential distribution.
