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.
为了推断中子慢化剂液氢中气化氢气泡的上升速度及影响因素，选取合适的工质进行了含气率的模拟实验。
To predict the rising velocity of hydrogen gas and the influencing factors, a suitable working fluid was determined for experimental simulation on the vold fraction of hydrogen in a neutron moderator.
