- However, excessive nitrogen ions irradiating reduced the activities of SOD, POD and CAT. 剂量过大时，SOD、POD和CAT活性下降；
- Low-energy nitrogen ion irradiation can efficiently induce single-, double- strand breaks with the ratio of 6 to 1(DSB/SSB), indicating that DSB may be the main production induced by low-energy heavy ions. 能量为30keV N~+照射干燥的质粒DNA能有效的产生单链断裂(SSB)和双链断裂(DSB)，有趣的是两种断裂的产额比，即DSB/SSB为6：1，说明双链断裂是低能离子引发DNA链断裂的主要形式。
