分析了具有非局部热非线性的圆柱对称介质支持的涡环孤子的显著特征。我们发现了这种涡旋孤子在传播时稳定的最大允许拓扑电荷的存在性：只有拓扑电荷m </= 2的涡旋环孤子是稳定的。这个显著的结果与样本的半径无关。
We analyze the salient features of vortex-ring solitons supported by cylindrically symmetric media with nonlocal thermal nonlinearity. We discover the existence of a maximum allowed topological charge for such vortex solitons to be stable on propagation: Only vortex-ring solitons with topological charge m </= 2 are found to be stable. This remarkable result holds independently of the radius of the sample.
