标题： The Origin of Galactic Cosmic Rays

摘要： 受近期关于银河系内10 TeV/核子以上的主要宇宙射线组分测量工作的推动，我们讨论了一种模型的唯象学，在该模型中，星系中有两种截然不同的宇宙射线加速器。氢和氦的能谱对比表明，这两种元素在整个100 TeV/核子的能量范围内并不具有相同的磁刚度谱，因此这两种占主导地位的元素来自不同的源。 显示英文摘要

摘要： Motivated by recent measurements of the major components of the cosmic radiation around 10 TeV/nucleon and above, we discuss the phenomenology of a model in which there are two distinct kinds of cosmic ray accelerators in the galaxy. Comparison of the spectra of hydrogen and helium up to 100 TeV per nucleon suggests that these two elements do not have the same spectrum of magnetic rigidity over this entire region and that these two dominant elements therefore receive contributions from different sources.
