摘要：
Surface tension difference is responsible for Marangoni condensation or Marangoni pseudo-dropwise condensation. The surface tension of ethanol solution of different concentration and temperature was investigated experimentally. The experimental investigation showed that the surface tension decreased with increasing temperature for different concontration solution; when temperature kept constant, the surface tension decreased with increasing concentration. Based on experimental value, a formula was fitted after considering the effect of ethanol mass concentration and temperature.
