【摘要】 本文给出了碳酸盐岩溶蚀研究的新方法,即动力学模拟实验方法。这一方法是依据碳酸盐（MeCO₃）——二氧化碳（CO₂）——水（H₂O）体系的两个水化学模型:方解石—CO₂-H₂O体系模型和白云石—CO₂—H₂O体系模型—而建立起来的。此二体系的状态和方解石或白云石的瞬时溶解速度仅受两个独立变量如Pco₂和pH的制约。因而所设计的动力学实验也仅需要观侧二个独立变量。此外本文还以实验结果为基础讨论了方解石溶解的动力学规律。实验结果表明,动力学模拟实验结果较为可靠,方法较为先进。它为进行碳酸盐岩溶蚀的定量研究提供了一个新方法。更多还原

【Abstract】 A new technique of dynamic simulation for study of the dissolution of carbonate rocks is presented on the basis’ of two hydrochemical models describing the dissolution process of carbonates in the system of carbonate-CO2-h2O:1, model of the calcite-co2-k2o system, and 2, model of the dolomite-co1-hjo system. Only two independent variables Pco2 and pH are needed for determination of the state of each system and the instantaneous dissolution rate of calcite or dolomite. Therefore, the dynamic experiment designed in this paper requires only the two variables obtained from observation. The dynamic law of calcite dissolution is also discussed in the paper. Results show that this experiment is successful, it develops the method presently used in China and provides a new way in quantitative study of the dissolution of carbonate rocks.更多还原
