| 摘 要： | 对SU（2）hedgehog skyrmion解析解Hyb（4/4）的参数和πNN耦合的计算方法进行了改进.改进后的解析解MHyb（4/4）与数值解更符合,误差也进一步减小,进而得知MHyb（4/4）为SU（2）Hedgehog skyrme模型更精确的解析解。

| Abstract: | The parameters of an analytical solution Hyb(4/4) for the SU(2) hedgehog skyrmion and the calculaton method of the π NN-coupling improved.The result shows a better agreement between themodified Hyb(4/4)(MHyb(4/4)) and numerical solution and has smaller error,lonseguently,it makes further understanding toward MHyb(4/4) is a more accurate analytical solution for the SU(2) hedgehog syrmion. |
