摘　　要：建立了一套直线透射式全截面测量装置,并测量了250—1400eV能区N_2分子的电子散射全截面,实验误差为3.5%。测量的结果与已报道实验和理论工作做了比较。A linear-transmission-type apparatus for measuring total cross sections of electron scattering by atoms and molecules has been set up. Measurements on N2 have been carried out for 250-1400eV electrons with an accuracy of 3.5%. The results have been compared with available experimental and theoretical values of the total cross section.
