So we have four choices in terms of initial and final energy levels, and also what it means - in terms of the electron — whether it's gaining energy or whether it's going to be emitting energy?

我们有这四个选项，各有不同的初始能量和末能量，它都是按照电子来说的，不管是失去能量还是得到能量？

The initial oxidation of pure iron and implanted samples which were overlapped energy ion–implanted with C ions was studied by auger electron spectroscopy (AES).

用俄歇电子能谱 （AES） 研究高真空室中纯铁和多能量叠加注碳纯铁表面与氧气吸附及初始氧化过程。
