求翻译：本文选用Co作为掺杂剂，由于Co在元素周期表中紧邻Fe元素,因此两者具有相似的电子层结构以及相近的原子半径,Co易取代Fe形成CoSi2[2]。是什么意思？

This selection of Co as a dopant, the Co and Fe in the periodic table close, so both have a similar structure and similar atomic electron shell radius, Co easy to replace the Fe to form CoSi2 [2].

Use this article as Saxons Co Co agent, the periodic table of the elements in the immediate vicinity, therefore, that the two persons Fe elements have a similar electronic configuration as well as similar to the atomic radius, Co Fe easily replaced CoSi formed [ 2] 2.

This article selects Co to take the doping agent, because Co in the periodic table close neighbor Fe element, therefore both have the similar electron shell structure as well as the close atomic radius, Co easy to substitute for Fe to form CoSi2[2).

This selection of Co as a doping agent, since Co close to Fe element in the periodic table, so the two have similar electron shell of a similar structure as well as Atomic RADIUS, Co easy replacement of Fe form CoSi2[2].

This selection of Co as a dopant, the Co and Fe in the periodic table close, so both have a similar structure and similar atomic electron shell radius, Co easy to replace the Fe to form CoSi2 [2].
