A program of comparing American (NASA) and Russian (ROSCOSMOS) space radiation transport codes has recently begun, and the first paper directly comparing the NASA and ROSCOSMOS space radiation transport codes, HZETRN and SHIELD respectively has recently appeared. The present work represents the second time that NASA and ROSCOSMOS calculations have been directly compared, and the focus here is on models of pion production cross sections used in the two transport codes mentioned above. It was found that these models are in overall moderate agreement with each other and with experimental data. Disagreements that were found are discussed.
一项比较美国（美国国家航空航天局，NASA）和俄罗斯（俄罗斯国家航天集团，ROSCOSMOS）空间辐射传输代码的计划最近已经启动，并且第一篇直接比较NASA和ROSCOSMOS空间辐射传输代码（分别为HZETRN和SHIELD）的论文最近已经发表。目前的工作是NASA和ROSCOSMOS计算结果第二次被直接比较，这里的重点是上述两个传输代码中使用的π介子产生截面模型。结果发现，这些模型相互之间以及与实验数据总体上有适度的一致性。文中讨论了发现的分歧。
