| 摘 要： | 于１９９１年３月－１９９２年６月间用滴体积法较系统地测定正已烷、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，计算与实验值相对误差≤０．５％。

| Abstract: | The respective alkane (n-c6, n-c7, n-c8,i-8, n-c12, n-c16 and kerosene, respectively)-seawater interfacial tension (I.T. ) in the temperature range of 16 - 40 °C and salinity range of 10 - 40 were determined with the drop-volume method by the authors from 1991 to 1992. The relative standard deviation of measured values <=0.5%. Seven empirical equations obtained on the basis of these measurements directly relates the alkanes-seawater I.T. with the temperature and salinity. The results show that all the alkanes-seawater I. T. decrease linearly with the rise of temperature. The salinity coefficient of the (n-c6, n-c7, n-c8, and i-c8)-seawater I.T. is positive, negative for n-c12 or n-c16. A model of adsorption at the alkane-seawater interface is presented for interpretation of this change of I .T. with salinity. |
