So if we wanna know the rate of change of neutrons as a function of time we will write this expression.
所以，当我们想要知道中子的变动率,那是时间方程，我们会写下这个表达式。163
So this is the fundamental equation that we can write that describes how neutrons in fact do accumulate.
所以，这是基本的等式,那是我们能写下来描述中子如何,积累的过程。163
So we get at the number of neutrons indirectly because we know the proton number here.
所以，我们可以间接得到中子数,因为我们知道质子数了。163
So we're looking only for the neutrons at energy E from this spectrum.
所以，我们不只在寻找能量 E的中子,从这个光谱中。163
