液体正癸烷，正十一烷，正十二烷，正十六烷形成微小的对称液滴的部分螺旋圆柱形纤维。当沿光纤沿着形成温度梯度时，液滴开始沿光纤沿着向冷区移动。对这一现象的解释与热毛细运动有关。排除了其他可能的机制。理论结果与实验数据吻合得相当好。
Liquid n-decane, n-undecane, n-dodecane, and n-hexadecane formed tiny symmetrical droplets on a partially wettable cylindrical fiber. When a temperature gradient was created along the fiber, the droplets began to move along the fiber toward the cold region. An explanation of the phenomenon is related to the thermocapillary motion. Other possible mechanisms were ruled out. The theoretical results and experimental data agree reasonably well.
