摘　　要：考虑到靶分子的不充分透明性和原子间电子云的重叠，提出了修正的可加性规则并用于计算分子N2O、NO2及CO2的散射的总截面．计算的能量范围为10～3000eV，并将计算结果与已有的实验结果和理论计算进行了比较．A new modified formulation of the Additivity Rule （AR） was proposed to calculate the total electron scattering cross sections for N2O,NO2 and CO2 Considering the overlapping between atoms in molecules and the not fully transparency of the molecules. The present calculation covers the range of impact energy from 10 to 3 000 eV. The results are compared with experimental data and other theories where available.

关 键 词：散射总截面 可加性规则 光学势方法
