因此，除非这些中子能够被充分减速，否则链式反应会停止。
As a result, the chain reaction will Peter out unless the neutrons can be slowed down sufficiently.
这些控制棒，由能够吸收中子的物质——硼制成，它吸收多余的中子，使链式反应停止。
These rods, made of neutron-absorbing materials such as boron, mop up excess neutrons and quench the chain reaction.
少量的裂变材料不能维持链式反应(绝大多数中子逃逸了)。
The few fissile materials could not maintain the chain type response (overwhelming majority neutron escape).
