Spatially overlapped coupled matter-wave bright solitons are considered in binary Bose-Einstein condensates with nonlinear optical lattices(NOLs) and study the properties of scattering patterns due to a localized defect. It is shown that spatially overlapped solitons become separated and exhibit different scattering patterns with the variation of inter-species interaction. The NOL interplays with the defect and tends to influence the scattering properties. However, the effect of NOL varies with strength of inter-component interaction. It is found that, if this interaction is weak then the scattering center gets shifted outside the defect. However, for a stronger inter-component interaction, the scattering takes place from the defect and leads to different scattering patterns.

非线性光学晶格二元玻色-爱因斯坦凝聚态缺陷引起的亮孤子散射

考虑了具有非线性光学晶格（NOL）的二元玻色-爱因斯坦凝聚中的空间重叠耦合物质波亮孤子，并研究了由于局部缺陷而导致的散射图案的特性。结果表明，随着物种间相互作用的变化，空间重叠的孤子变得分离并表现出不同的散射模式。 NOL 与缺陷相互作用，往往会影响散射特性。然而，NOL 的效果随组分间相互作用的强度而变化。研究发现，如果这种相互作用较弱，则散射中心会移至缺陷之外。然而，为了增强组件间的相互作用，散射会从缺陷处发生，并导致不同的散射模式。
