在非线性热介质中嵌入抛物线纵向弯曲波导阵列支持局域定态孤子。局域化是由于无限范围非局域非线性对曲率效应的抑制。解析地给出了定位准则。孤子沿弯曲轨迹稳定传播，无弯曲损耗，其位置受波导曲率影响显著。这些孤子是第一个在弯曲波导中遇到的静止局域孤子的例子。
A parabolically longitudinally bending waveguide array imprinted into thermal nonlinear media is found to support the localized stationary solitons. The localization results from the suppression of a curvature effect by the nonlinearity with an infinite-range nonlocality. The localization criterion is given analytically. Solitons propagate stably along a curved trajectory without bending loss, and their locations are significantly influenced by the waveguide curvature. These solitons represent the first example of stationary localized solitons encountered in curved waveguides.
