摘要
The bonded types and the mechanism of the borides’ structures of the transition metalshave been a very interesting problem to scientific workers in various fields of solids, met-als, physics and chemistry at home and abroad. It has evoked much controversy. It isvery difficult to calculate the iron boride in the energy band theory because of the com-plexity of its structure. The analysis of valence electron structure of FeB is given in
