| 摘 要： | 本文利用非拓扑粒子模型计算了核物质环境中的核子(孤粒子)的尺度增量等物理量。这些结果可被认为是由核物质中真空性质的变化引起的。相对论性核平均场论可以用来研究核介质中与夸克相互作用的标量场。计算结果能够合理地符合与质量数相关的轻子与核的深度非弹散射的测量。

| Abstract: | Some static physical quantities, e. g. the size increment of a nucleon (soilton) embedded in nuclear environment, are calculated in a non-topolgical soliton model. These results may be understood as steming from the changing of vacuum properties in the presence of the nuclear environment. The relativistic nuclear mean field theory may be used to estimate the scalar field felt by a quark in nuclear medium. The calculated results are in reasonable agreement with the measurement of the mass number A-dependence in the lepton deep inelastic scattering on nuclei. |
