重离子生物效应研究中的一些基本物理问题

Some Basic Physical Matters in Research into Biological Effects of Heavy Ions

从原子物理学理论出发，论述了重带电粒子（重离子）与生物介质相互作用的某些物理过程，对重离子生物效应研究中主要涉及的一些基本物理问题进行了讨论．它们是：重离子的能量损失；δ电子的发射；电子输送和径迹晕（或阴影）；浓缩相效应和径迹芯．

Some physical processes of the interaction between heavy charged particles(heavy ions) and biological medium are described according to the theory of atomic physics in the paper.Basic physical matters involved in research into the biological effects of heavy ions are discussed.They are energy loss of heavy ions,δ-electron emission, electron transport and track halo(penumbra),condensed phase and track core.
