摘要	Water circulation system with the almost same element composition and socket type were adopted in coral Acropora culture under different seawater pH conditions and the experimental data of the relationship between boron isotopic compositions of coral and seawater pH were obtained by thermoelectric ionization mass spectrometer. From the correlations between alpha(carb-3) of coral and pH of cultured seawater, alpha(carb-3) was not a constant but related to pH, indicating that B(OH)(3) also incorporated carbonate. Therefore, the theoretical formula could not be used to calculate the seawater pH value from the delta B-11(carb) value of the measured marine biological carbonate. The method using the empirical equations obtained experimentally to calculate the seawater pH value would be an alternative. In addition, a mixed precipitation of inorganic CaCO3 and Mg(OH)(2) was found in aquaculture tanks with high pH value and the delta B-11 of the solid was significantly higher than that of cultured seawater. The result indicated that the presence of Mg(OH)(2) had a significant effect on the boron isotope fractionation, which deserved our attention.
