摘要: 考察了包含手征流非对易项的拓展Skyrme模型。在推导出相应Skyrme模型运动方程的基础上对模型中的球对称Skyrmion孤子进行了数值模拟。对模型进行零模(Zero-mode)量子化之后，计算核子的若干静态性质，并讨论了拓展Skyrme模型中手征流非对易项与QCD之间的联系。 This paper considers the extended Skyrme model with the anticommutator of the chiral current. By deducing the equations of motion of extended Skyrme model， the spherically symmetric Skyrmion was numerically simulated. After the Zero-mode quantization of the model， the static properties of nucleons were calculated and the connection of the anticommutator of the chiral current with QCD was discussed.
