- So if you take a certain volume and you have a certain amount of material, let's just take the fission cross section as the issue.
所以，如果你得到一定的容积，你有一定量的材料，我们就把裂变横截面当做问题。 - 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。 - Evaluation of Snell Experiments& Average Fission Cross Section Ratio of Equilibrium Spectrum in a Natural Uranium
评价Snell实验&大块天然铀介质中平衡谱的平均裂变截面比 - The contribution to the total fission cross section arising from transfer is about 10%.
在总裂变截面中，转移裂变的贡献约为10%。 - The phenomenon of longitudinal fission seldom occurred during the process of tube plug drawing mill compared with empty-sunken steel tube. The problem which seldom cause transverse fissure in form of partial failure owing to uniform distribution of axial stress in cross section.
与空拔相比较，在短芯棒拔制过程中，纵裂现象一般不会发生，由于钢管轴向应力在横截面上分布均匀，一般也不会出现以局部破坏形式出现的横裂现象。 - In this paper we prove uniqueness and existence of the optimal fission cross section, and give the optimality condition.
给出了最优解的存在性、唯一性以及最优解的充分必要条件。
