在这篇文章中,我们确定了任意参数选择下仿射Weyl型$\TB_{2}$和$\Tg_{2}$的Kazhdan-Lusztig胞格的划分。利用这些划分,我们证明了Bonnafe的半连续猜想对这些群成立.
In this paper we determine the partition into Kazhdan-Lusztig cells of the affine Weyl groups of type $\tB_{2}$ and $\tG_{2}$ for any choice of parameters. Using these partitions we show that the semicontinuity conjecture of Bonnaf\'e holds for these groups.
