Thermocapillary migration describes a phenomenon where a liquid droplet spreads from warm to cold regions due to the interfacial tension gradients. Since the contact angle hysteresis effect is involved during the migration process, we consider the hysteresis effect and rectify the theoretical model to predict the migration velocity on solid surfaces. By conducting migration experiments on surfaces with different magnitudes of the hysteresis effect, we verify the validity of the theoretical derivation. This study advances the understanding of the interfacial phenomenon of thermocapillary migration, moreover, offers an insight into the migration capacity of different materials and guides the design of key components associated with the thermal gradients.

热毛细管迁移描述了一种现象，其中由于界面张力梯度，液滴从温暖区域扩散到寒冷区域。由于迁移过程涉及接触角磁滞效应，因此我们考虑了磁滞效应，并修正了理论模型以预测固体表面的迁移速度。通过在具有不同大小的磁滞效应的表面上进行迁移实验，我们验证了理论推导的有效性。这项研究不仅增进了对热毛细管迁移的界面现象的理解，而且还提供了对不同材料迁移能力的深入了解，并指导了与热梯度相关的关键组件的设计。
