这样如果你来估算，这样的小体积元的整体数目，就有10，的30次方的数量级。

So if you look at the total number of little volume elements of this sort, it's on the order of 10 to the 30th.

将有关参量和实验测量值代入这些解，所估算的脉冲宽度数量级与实验显示值能较好地相符合。

The pulse width has been estimated by substituting the parameters and experimental values into the solutions, and the result agrees with that of the experiments within an order of magnitude.
