通过适当的流体动力场方程与实际水平边界条件的数值积分，确定了具有不同扩展和唯一选择宽度的亚临界和超临界局域行波(LTW)对流态的结构和动力学。一个大尺度的平均浓度电流回路对LTW有显著影响。它产生的浓度分布阻碍了LTW脉冲的传播，因此群速度很小，但有限
The structure and dynamics of both subcritical and supercritical localized traveling-wave (LTW) convective states with different extensions and uniquely selected width are determined by numerical integration of the proper hydrodynamic field-equations with realistic horizontal boundary conditions. A large-scale mean concentration current loop influences the LTW significantly. It generates a concentration distribution that hinders propagation of the LTW pulse, so that the group velocity is small but finite
