　　Total cross sections of electron scattering by eight molecules NF3, PF3, N(CH3)3, P(CH3)3, NH(CH3)2, PH(CH3)2, NH2CH3 and PH2CH3 in some structural similarities are calculated at the Hartree-Fork level by employing the modified additivity rule approach.The modified additivity rule approach takes into considerations that the contributions of the geometric shielding effect vary as the energy of incident electrons, the targets molecular dimension, the number of electrons in the molecule and the number of atoms constituting the molecule.The present investigations cover the impact energy range from 30 to 5000 eV.The quantitative total cross sections are compared with those obtained by experiments and other theories.
