| 摘 要： | The specific gravity of 13 sea water samples at 25℃ from the estuary of the Changjiang River has been determined by the pycnometer method. The results are consistent with the values computed from chlorinity by Knudsen's tables within the experimental error of the method, and are lower on an average of about 0.02 in sigma-25 than values computed from salinity by the equation of Cox et al. (1970). The standard deviation of our measurements is estimated at ±0.01 in sigma-25.The differences between the present results and the values computed from chlorinity by the equation of Cox et al. (1970) imply that, for water of the same chlorinity, the sea water at the estuary of the Changjiang River tends to have a lower concentration of dissolved substances than that of the ocean water.Our work shows that the Knudsen's tables may apply to the sea water at the estuary of the Changjiang River and also provides an experimental evidence that the new oceanographic tables can be applied to the studies on the sea water |

| Abstract: | The specific gravity of 13 sea water samples at 25℃ from the estuary of the Changjiang River has been determined by the pycnometer method.The results are consistent with the values computed from chlorinity by Knudsen's tables within the experimental error of the method, and are lower on an average of about 0.02 in sigma -25 than values computed from salinity by the equation of Cox et al. (1970).The standard deviation of our measurements is estimated at ±0.01 in sigma -25. The differences between the present results and the values computed from chlorinity by the equation of Cox et al. (1970) imply that, for water of the same chlorinity, the sea water at the estuary of the Changjiang River tends to have a lower concentration of dissolved substances than that of the ocean water. Our work shows that the Knudsen's tables may apply to the sea water at the estuary of the Changjiang River and also provides an experimental evidence that the new oceanographic tables can be applied to the studies on the sea water of China Sea area. |
