We classify oriented ribbon 2-knots of 1-fusion with length up to six. We show the difference by: the Alexander polynomial; the trace set, which is obtained from the representations of the knot group to $\mathrm{SL}(2,\mathit{C})$; the twisted Alexander polynomial.

长度不超过6的带状2结1融合的分类

我们将长度不超过6的定向1融合带2结分类。我们通过以下方式来表明差异：亚历山大多项式；跟踪集，它是从结组的表示获得的$\mathrm{SL}（2，\mathit{C}）$; 扭曲的亚历山大多项式。
