星际空间中宇宙线重新加速的研究

A Study of Cosmic-Ray Reacceleration in the Interstellar Space

本文从能量空间中具有加速的宇宙线传播方程出发,给出了泄漏箱模型图象中高能原初谱及次级与原初核之比的数学表达式,我们的结果表明星际空间中宇宙线的重新加速可能是存在的,没有必要考虑次级和原初的不同空间分布的概念。

Starting from the cosmic-ray transport equation which contains acceleration in energy space the mathematical expressions for high energy primary spectra and secondary pramary nuclei ratios in the leaky box model are dirived. Our study shows that cosmic-ray reacceleration in the interstellar space could be taking place and there is no need to consider the difference between the space distributions of secondary and primary nuclei.
