摘　　要：利用活动标架法与Ｌａｐｌａｃｉａｎ特征值方法研究了具有常数平均曲率超曲面的稳定性问题。给出了三维拟常曲率流形中具有常数平均曲率超曲面的共形度量的高斯曲率之上界估计。In this paper, stabilities of hypersurfaces with constant mean curvature were studied bymeans of methods of moving frame and eigenvalues of the Laplacian. Some estimates ofGaussian curvature of conformal metric of 2-dimensional hypersurfaces with constant meancurvature immerged in 3-dimensional manifold of quasi-constant curvature were obtained.Sufficient conditions for a simply-connected domain of 2-dimensional hypersurfaces with cons-tant mean curvature immerged in 3-dimensional manifolds of quasi-constant cvrvature to bestable were proved.
