And that is measured as a macroscopic cross section of absorption thermal divided by the integral of all energies in terms of absorptions.

那是被测量的，作为吸收热能的，宏观横截面，除以全部的，吸收的能量的乘积。

You have what we call a total cross section which is the total probabilities of either scattering or absorption. These are the two phenomenon that we are talking about.

你们有我们称为总横截面的,那是散射或者吸收的总概率,这些是我们要谈论的,2个现象。

And then of course as part of the absorption we have a fission cross section which, as I said earlier, is what we want to focus on so we can make some power and some heat.

当然作为吸收的一部分，我们有裂变横截面，那是，我之前说的，是我们想要关注的，所以我们可以创造，出一些动力和一些热量。
