电离径迹 meaning in English

ionization path
ionization track

Compared with low - let radiation , heavy ion radiation has a different structure of ionizing track through a matter . its complex ionizing tracks lead to multiple ionization events within nanometer regions of the target , resulting in complex damage
与低let辐射相比，重离子通过物质时有着完全不同结构的电离径迹，径迹结构较为复杂，所引起的损伤机制极为复杂。
