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。
Studying the absorption characteristic of SO2 flue gas is the base of online monitoring. The temperature and pressure have different effect on absorption cross-section.
研究SO2吸收性是光谱法在线监测的基础，被测环境的压力和温度等因素对SO2吸收截面有不同程度的影响。
When the upper state population is not reversed, the channel with greater ratio of emission and absorption cross-section has greater competitive advantage.
当上能级粒子数处于未反转分布态时，具有较大的发射截面与吸收截面比值的波长信道拥有相对较大的增益竞争优势。
