Parameterizations of double nucleon removal from the electromagnetic and strong interactions of cosmic rays with nuclei are presented. These parameterizations are an extension of previous single nucleon removal parameterizations and combined they represent the dominant part of the electromagnetic dissociation encountered by a cosmic ray on its traversal through matter. Such parameterizations should be very useful in studying cosmic-ray transport through the interstellar medium, the Earth's atmosphere, spacecraft walls, and extraterrestrial matter.

宇宙射线核的截面参数化。二。双核子去除。

提出了从宇宙射线与原子核的电磁相互作用和强相互作用中去除双核子的参数化。这些参数化是先前单个核子去除参数化的扩展，并且它们组合起来代表了宇宙射线在穿过物质的过程中遇到的电磁解离的主要部分。这样的参数化在研究通过星际介质，地球大气层，航天器壁和外星物质的宇宙射线传输中应该非常有用。
