Abstract: For measuring surface-tension by means of drop- volume method,the terminal radius of measuring buret of drop-volume must be determined first.Owing to the unity between the values of the terminal radius getting out of triply distilled water or benzene and the V/r3-Ftable,a method which can be used for determining the terminal radius in the absence of micrometer is supplied.

Key words: Drop-volume method, Surface-tension, Measuring buret of drop-volume, Terminal radius
