中文摘要：
讨论了是光束在（1＋1）维的热致非局域介质中的传输，此介质在中心处被分为两部分，两部分的线性折射率是不同的．发现在中心处的界面附近存在多阶稳定的界面孤子．本文研究的是五阶和六阶界面孤子，它们都存在三种不同的孤子解．三种孤子解的波形、束宽、光束重心、存在和稳定区间都是不相同的．五阶孤子的三种解都存在稳定区间，并且其中两个解存在共同稳定区域．然而六阶孤子只有其中一种解存在稳定区间．
英文摘要：
We consider a one-dimensional thermal nonlinear medium with a step in the linear refractive index at the sample center. It is found that there exist multipole interface solitons around the interface of the sample. In this paper, we address the existences of three types of solutons for fifth-order and sixth-order interface solitons. The three types of interface solitons have diferent pofiles, beam widths, mass centers, existence and stability regions. The three types of fifth-order solitons each have a stability region, and two of them have the same regions. However for sixth-order interface solions, only one type solution has a stability region.
