利用数值的方法求解了光折变非线性方程，研究了类行波空间孤子非相干相互作用的规律。结果表明：类行波孤子的非相干相互作用表现为相互吸引，并伴有能量耦合，两束非相干类行波孤子在晶体中形成Y型波导，同时互相导引部分光能量。当初始间距较大时，两柬光并行传播，传播一定距离后越来越多能量耦合到另一束光诱导的波导中；当两束类行波孤子初始间距较小时，两束光会来回交叉扭结在一起；当两束光的间距进一步减小时，两束光相互吸引相遇，然后交叉而过。

The rules of incoherent interactions of photorefractive travelling-wave-like spatial solitons are investigated by solving nonlinear equation numerically. The results show that the interaction solitons performance for mutual attraction and energy coupled. A Y-waveguide is formed in the crystal when two travelllng-wave-like solitons interact, at the same time the partial energy guided by Y-waveguide. Larger when the initial distance between two solitons, they propagate in parallel, and more and more energy is coupled into another beam induce waveguide with the increase in distance. Smaller when the initial distance between two solitons, they would wrap across. When two beams to further reduce the distance, they meet due to attraction, and then cross over.
