宇宙射線陰電子及陽電子宇宙射線是從天空向地球射來的帶電質點的狂流。這些質點中,大約有80％是質子,近乎20％是氦核,即α質點。除此之外,大約有1％的質點是較重元素的原子核。這些質點的能量,在大多數的情形,是在數量級10~9—10~11電子伏特之間,但也有能量極大,達到數量級 Cosmic rays Yin electrons and positron cosmic rays are the fiery currents of charged particles shot from the sky towards the earth. Approximately 80% of these particles are protons and nearly 20% are helium nuclei, ie, alpha particles. In addition, about 1% of the particles are nuclei of heavier elements. The energy of these particles, in most cases, is on the order of 10 to 9-10 to 11 electron volts, but there are also energies that reach orders of magnitude
