于1991年3月－1992年6月间用液体积法较系统地测定正己烷、正庚烷、正辛烷、异辛烷、正十二烷、正十六烷和煤油与海水在不同的温度（16－40℃）和盐度（10—40）范围内的界面张力，测定值的相对误差≤0．5％。对数据进行统计处理后，归纳出所研究烷烃－海水界面张力与温度和盐度的经验关系式，计算值与实验值相对误差≤0．5％。
N-Heptane, n-octane, iso-octane, n-dodecane, n-hexadecane and kerosene were measured with the seawater at different volumes from March 1991 to June 1992 Interfacial tension in the range of temperature (16-40 ℃) and salinity (10-40), the relative error of the measured value ≤0.5%. After statistical processing of the data, the empirical relationship between the interfacial tension of alkane - seawater and temperature and salinity was summarized. The relative error between the calculated value and the experimental value was ≤0.5%.
