摘    要：本文对曲线拟合座滴图象求解界面张力的数学方法进行了研究,提出了自座滴子午线座标求界面张力,润湿角及液滴体积的计算方法与相应的计算机程序。讨论了座滴法测量界面张力的误差。

Abstract: The present paper studies mathematically the method of calculating interfacial tension by curve fitting to the picture of sessile drop. This paper presents a com- putation method and program for calculation of interfacial tension, contact angle and volume of the liquid drop from the coordinate of meridian of sessile drop. The error of measurement of interracial tension by the sessile drop method is dis- cussed in this paper.
