摘　　要：表面张力是液体的基本物化性质之一。采用自制的滴体积法实验装置,以蒸馏水的表面张力作为标准,检验了其精确性。结果表明,相对误差在0.5%以下,能满足实际的需要。Surface tension is one of the basic physicochemical properties of liquids. The apparatus of drop volume method was made in this paper, accuracy of which was verified according to the literature value. The results showed that the measurement equipment for the surface tension of liquid can satisfy the practical need within the experimental error of 0.5%.
