慢化剂，又称中子减速剂。为使核裂变反应得以有效地进行，一种被加入反应堆内用来减慢中子运动速度的物质。
Firstly, the calculation is carried out for those elements that affect heating such as the kind of moderator, moderator cell material and so on. The optimized selection is provided.
利用该方法分别对影响核发热和冷中子增益的各种因素如：慢化剂、冷包材料、冷包形状和正仲氢比例等进行了计算、分析和优化。

所以在反应堆里，典型的慢化剂,热能反应堆是氘和氢。
So typical moderators in reactors thermal reactors are deuterium and hydrogen.
通过实验发现，对于具有硼慢化剂的铁硼水反射层堆芯，堆芯具有正的反应性效应。
From these results, it is concluded that the reflector with steel and boron water has positive reactivity effect on the core with boroned moderator.
你能够正确地减慢中子，通过将它们散射，用一个恰当的，慢化剂，这样它们就不会损耗或者被吸收。
And that you can appropriately slow down the neutrons by scattering them with an appropriate moderator such that they're not lost or absorbed.
