Then you have to figure out, once you design basic power distribution you have to make sure you have what's called reactivity control.
然后你们需要研究出，一旦你设计了基本的，能量分布，你就必须确保，你得到了反应控制。
The power coefficient of reactivity (PCR) is a measure of whether a particular reactor's nuclear neutron population will tend to increase or decrease after an increase in the reactor's power.
PCR是一座反应堆的核中子数会在反应堆能量增加后增加或减少的衡量标志。
The results indicate that fuel temperature changing more slowly than nuclear power makes reactivity negative feedback not to restrain power changing, and then power concussive progress comes to being.
结果表明：燃料温度变化相对于功率的变化缓慢且滞后，燃料温度反应性负反馈不能及时抑制功率的变化是形成系统参量产生衰减振荡的主要原因。
It is indicated that the peak power for pulse varies as the square and energy released linearly with the reactivity insertion.
计算结果表明，脉冲峰功率与反应性引入量的平方成正比；一次脉冲释放能量与反应性引入量成正比；
