【摘要】 本文用超新星爆发产生的原初宇宙线电子在星际介质中的均匀扩散模型来研究空间各点的非定态电子能谱。扩散系数采用与磁流波共振散射的机制半经验定出。把解出的结果与地球附近测得的电子能谱比较,定出抛射时的电子谱指数Γ～2。又在电子与2.7°K背景光子场的逆康普顿散射形成X扩展源的假设下,推导出X扩展源的能态函数,从而得到地球附近的X射线能谱。上面定出的Γ～2也能很好地说明蟹状星云的X射线谱指数。更多还原

【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.更多还原
