Abstract：
Non-steady state electron spectrum in interstellar medium is investigated by using the model of isotropic diffusion of primary cosmic electrons originated from explosion of supernovae. The diffusion coefficient was determined semi-experientially according to particles resonant scattering on the turbulent by dromagnetic wave. Comparing the solution of the diffusion equation with the electron spectrum which was measured near the earth, we derived the index Γ of the electron spectrum to be Γ～2. Assuming that the electron inverse Compton scattering on 2.7°K background field forms diffusion X-ray sources, we deduce the energy-state function, and then obtain the X-ray spectrum near the earth. The index Γ～2 decided above can also explain the X-ray spectrum index of Nebuler.
