使用寿命预计数与原先估计数有差异的，应当调整固定资产使用寿命。

If there is any difference between the expected useful life and the previously estimated useful life of a fixed asset, the expected useful life of the fixed asset shall be adjusted.

因此计数管的使用寿命不能仅以允许通过计数管的总电荷表示。

Thus the counting life of a counter can not be expressed merely in terms of quantity of electric charge passing through it.
