<p> The ability to predict the formation and dissolution of solids (minerals and precipitates) in aquatic systems is currently constrained by limitations of the traditional thermodynamic approach. A new approach based on the kinetics of the underlying chemical reactions is expected to overcome these limitations and greatly improve the ability to describe these processes. This new fundamental knowledge will be useful in many diverse fields including aquatic geochemistry, soil chemistry, water engineering, and nanotechnology. The new approach will be specifically applied to improve understanding of processes related to the globally significant environmental issues of marine iron fertilisation, ocean acidification and acid sulfate soils.</p>

&lt；p&gt； 目前，预测水生体系中固体(矿物和沉淀物)的形成和溶解的能力受到传统热力学方法的限制。一种基于潜在化学反应动力学的新方法有望克服这些限制，并极大地提高描述这些过程的能力。这一新的基础知识将在许多不同的领域有用，包括水生地球化学、土壤化学、水工程和纳米技术。新方法将具体应用于提高对海洋铁肥、海洋酸化和酸性硫酸盐土壤等全球重大环境问题相关过程的理解。
