摘　　要：前人曾用重离子束注入生物小分子 ,借助先进的仪器分析手段 ,对重离子注入质量沉积进行了初步研究 ,但质量沉积对处于生命状态下的活生物体组织细胞和生物大分子所带来的生物学效应 ,即质量沉积效应的研究还未见报道。将来可用放射性重离子束注入活细胞和生物分子 ,借助放射自显影示踪。Researchers have used heavy ion beams to implant small biomolecules, followed by advanced instrumental analysis to make preliminary studies on mass deposition induced by ion implantation. But research reports on the biological effects, i.e. mass deposition effects induced by mass deposition in living tissues, cells and macro-biomolecules haven' t been delivered hitherto. In the near future radioactive heavy ion beams will be possible to implant living cells and biomoleules, and autoradiography, radioactive measurements and molecular biological techniques will be employed to further studies on the effects.
