一个醇（戊醇）液滴表现出自发运动的水溶液，由溶质马兰戈尼效应驱动。我们发现，这种液滴运动的模式的变化取决于水相的温度。当水相的温度为20 ℃时，体积为1 μ l的液滴表现出矢量运动，而当温度为25 ℃时，液滴表现出不规则运动。我们讨论了模式变化与戊醇在水中溶解度的关系。
An alcohol (pentanol) droplet exhibits spontaneous motion on an aqueous solution, driven by a solutal Marangoni effect. We found that the mode of such droplet motion changes depending on the temperature of the aqueous phase. When the temperature of the aqueous phase is 20 degrees C, a droplet with a volume of 1 mu l exhibits vectorial motion, whereas when the temperature is 25 degrees C, the droplet exhibits irregular motion. We discuss the mode change in relation to the solubility of pentanol in water.
