本研究在Skyrme模型中采用三维卡西尼卵形线拟设来拉伸球对称解，发现静态能量与纵向形变参数呈线性关系，斜率约0.14 GeV²，与禁闭模型的弦张力一致。
AI 中文摘要
我们研究了Skyrme模型中球对称解的拉伸。将卡西尼卵形线的三维推广作为扩展的拟设。静态能量对纵向形变参数的线性依赖关系被获得，其斜率约为σ≈0.14 GeV²，这与从各种禁闭模型已知的弦张力吻合良好。
英文摘要
We investigate the stretching of a spherically symmetric solution in the Skyrme model. The three-dimensional generalization of the Cassini ovals is considered as ansatz of extension. The linear dependence of static energy on the longitudinal deformation parameter is obtained with a slope $σ\approx 0.14\ \mathrm{ GeV}^2$, which is in good agreement with the string tension known from various models of confinement.
