MEANING OF 鏈式反應
鏈式反應 (链式反应)
chain reaction
铀﹑钚等重元素的原子核受中子轰击时﹐裂变成几个碎片﹐并放出两个到三个中子﹐这些中子再打入铀或钚的原子核﹐再引起裂变﹐这种连续不断的核反应叫"链式反应"。链式反应能产生巨大的能量。也叫支链反应或连锁反应。 由于一个单独分子的变化而引起一连串分子变化的化学反应。如燃烧过程﹑爆炸过程。也叫链反应或连锁反应。 由少数光子引起许多原子辐射的过程。

EXAMPLE SENTENCES

铀原子停止了链式反应

The uranium "stopped" the chain reaction.

有点像我们所说的链式反应

Sort of what was we call a 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).

控制棒会吸收路子减慢链式反应,降低核反应的能量释放,进而关掉反应堆。

The control rods soak up the neutrons that mediate the chain reaction which produces most of a reactor's energy, shutting it down.

功率的激增引起了反应堆的链式反应,反应堆的堆芯燃烧起来。

A surge of power caused a chain reaction that set the reactor core on fire.

即便控制棒已经全部插入(百步穿杨?)去终止链式反应,那些反应堆依旧非常的热(还记得760度么)。

Even though the control rods were fully inserted to slow the fission chain reaction to a stop, the reactor was still extremely hot.

该计划致力于武器化:虽然制造在核原料中引发链式反应的设备是一件高精细度的工作。

That programme was about “weaponisation”: the fiddly business of making a device that can set off a chain reaction in nuclear fuel.
