Now what we're gonna cover in this lecture are some basics such as cross sections, the fundamentals of the fission process.

现在，我们将要在这节课完成的，就是一些基础像是横截面，裂变过程的基本原理。

The nuclear reaction can be controlled utilizing rods made of neutron-absorbing material, such as boron, essentially shutting down the fission process.

核反应可以通过使用由吸附中子的材料构成的棒条，比如硼，来减慢裂变过程，从而控制其反应。

The fuel is abundant, the process safe and the waste, though radioactive, is far less noxious than the stuff left over from fission.

燃料储量丰富，过程安全，废料尽管有放射性，但同裂变产生的废料相比，有害程度要小得多。

But in Dr Rostoker's reactor, the helium nuclei created by the process of light fission would be speedy enough to escape from the ends of the ellipsoid, where the magnetic field is weakest.

This reactor does not use fission, the process of splitting atoms into smaller elements employed by every commercial power reactor currently operating on earth.
