Let me now try and introduce the Boltzmann equation because it basically gives us a much deeper appreciation than diffusion theory can in terms of what's going on.

我现在尝试介绍波尔兹曼方程，因为它给你们一个比扩散理论，更深刻的理解，在解释，发生的事情方面。

This is called the Boltzmann equation.

它就是玻尔兹曼公式。

Now in the Boltzmann Equation we wanna track neutrons so we need to take the flux and divide it by the velocity.

现在，在波尔兹曼方程方程里，我们要追踪中子，所以我们需要，能将流量拿出并除以速率。
