用数值方法研究了1+1维多真空标量场论中的扭结碰撞。我们感兴趣的磁区壁模型包括两个标量场和一个由非对称双势垒和(双)Sine-Gordon势建立的势项，以及一个相互作用项。根据初始扭结设置和撞击速度，该模型允许大范围的散射行为。扭结可以相互排斥，湮灭，形成真或假的域墙，并相互反射。
We investigate numerically kink collisions in a 1 + 1 dimensional scalar field theory with multiple vacua. The domain wall model we are interested in involves two scalar fields and a potential term built from an asymmetric double well and (double) sine-Gordon potential together with an interaction term. Depending on the initial kink setup and impact velocities, the model allows for a wide range of scattering behaviours. Kinks can repel each other, annihilate, form true or false domain walls and reflect off each other.
