Rayleigh-Bénard-Marangoni convection instability transitioning between hexagonal Bénard cells and longitudinal roll states, rendered as advected thermal filaments with negative void space. 对流胞与涡卷态的相变，在流函数漂移中显影出热对流的丝状骨架与虚空负空间。
Surface tension drops along the heated terrace floor, opening honeycomb cells that stretch into parallel ruts under lateral wind. 灰壤下层受热，表面张力梯度将六角形的 Bénard 腔室拉扯成顺风平行的涡卷。 The fluid does not spill; it tears itself into skeletal margins and leaves cold, hollow eyes.
Tested the bifurcation between hexagonal $C_6$ symmetry and longitudinal roll regimes by modulating the thermocapillary Marangoni term against thermal buoyancy. 丝状骨架的保留依赖于对涡度梯度的负向阈值截断，用低密度字符 (`·`, `:`, `.`, `~`) 承载扩散尾迹，避免了胞元中心在高对流区坍缩为实心块。 Motion delta (0.78) confirms smooth phase slipping along cell slip-lines.
