The results calculated are believed to be in agreement with thosemeasured experimentally in previous literature. The formulas to evaluate S_c(E) foralloy, boride containing or CsCl structure have been also derived. However, theseare favourable to only mono-or bi-borides, but not for borides with complex struc-ture such as Cr_5B_3 or W_2B_5. The coefficient of S_c(E) for alloy of CsCl structuredeviating from Bragg's S_c(E) is directly proportional to charge transfer in alloy.The larger the charge transferis, the stronger the metallic bond is. Hence, theS_c(E) created by metallic bond in alloy will be increased; there is a tendency forit to increase with increasing separation of two components in alloy on either sideof Cr group at same periods; and the tendency is larger when the two componentsare in different periods.
