虽然对于宇宙射线的银河起源（E k ~ 3× 10 15 eV）和能量在~ 10 19 eV以上的宇宙射线的河外起源有一定程度的共识，但关于中间能量区域宇宙射线起源的争论受到的关注要少得多，主要是因为在定义这样一个区域时固有的模糊性。能量范围在10 - 17 eV和~ 10 - 19 eV之间，很可能是从银河到河外宇宙射线发生转变的地方。因此，这些粒子的起源，虽然从物理学的角度来看是最重要的，但也是最难研究的方面之一。在这里，我将说明一些关于这些粒子加速的地点的想法，以及他们的研究可能有助于回答的问题，包括超高能量宇宙射线的起源。
While there is some level of consensus on a Galactic origin of cosmic rays up to the knee (E k∼ 3× 10 15 eV) and on an extragalactic origin of cosmic rays with energy above∼ 10 19 eV, the debate on the genesis of cosmic rays in the intermediate energy region has received much less attention, mainly because of the ambiguity intrinsic in defining such a region. The energy range between 10 17 eV and∼ 10 19 eV is likely to be the place where the transition from Galactic to extragalactic cosmic rays takes place. Hence the origin of these particles, though being of the highest importance from the physics point of view, it is also one of the most difficult aspects to investigate. Here I will illustrate some ideas concerning the sites of acceleration of these particles and the questions that their investigation may help answer, including the origin of ultra-high-energy cosmic rays.
