%X Considering the overlapping among atoms in the molecule and the not full transparency of the molecule by electron, we propose a new formulation of the additivity rule (AR). Here the new AR is employed to calculate the total cross sections (TCS) for electron scattering on hydrocarbon molecules C_2H_2, C_2H_4, C_2H_6, and C_3H_8 over an incident energy range of 10－2000eV. The results are compared with the experimental data and other available theoretical calculations. This gives good agreement.
