摘　　要：本文总结了晕和皮等奇异核子结构研究的现状 ,介绍了发现晕和皮现象的实验证据。然后集中介绍了利用奇异核反应总截面的实验测量和理论模型 ,从中提取奇异核物质半径、核内核子分布以及介质中的核子 核子碰撞截面等重要信息 ,我们将特别强调通过实验测量和理论模型之间的联系来研究奇异结构性质。We review the study of exotic nuclear structure such as halo (skin). First we introduce the experimental evidence of the existence of neutron halo (skin) and some correlative models including their physical foundation and calculation method. Afterwards, we concentrate on extracting some fundamental information, such as the nuclear matter radii, the density distributions of neutrons and protons in nucleus and the in?medium nucleon?nucleon cross section etc, by using the experimental measures and theoretical models about total reaction cross section of exotic nuclei. We emphasize on the relation of experimental measurement to the theoretical model.
