虽然已经进行了许多氢气还原月球土壤的实验，但还没有系统的热力学分析来设计和优化这些实验。将热力学模型应用于模拟月壤-氢气系统，详细分析和讨论了该系统的热力学行为。计算表明，铁是唯一可以从月球土壤中大量提取的金属。该系统中的氢气量极大地影响着提铁和制水的过程。但在此过程中，系统压力的影响可以忽略不计。研究了月壤中金属铁和水的产生量随温度和氢含量的变化规律。此外，这些计算还从热力学角度解释了月球表面的金属铁。
Although many experiments have been performed to reduce the lunar soil by hydrogen, no systematic thermodynamic analysis has been developed to design and optimize these experiments. Applying a thermodynamic model to the system of simulant lunar soil and hydrogen, this study analyzes and discusses the thermodynamic behavior of the system in detail. The calculations demonstrate that iron is the only metal that can be extracted significantly from the lunar soil. The amount of hydrogen in the system drastically affects the processes of iron extraction and water production. However, the effect of system pressure can be neglected in the process. The yields of metallic iron and water from the lunar soil as functions of temperature and hydrogen content are investigated in this study. Additionally, the calculations explain the metallic iron on the surface of the moon from the thermodynamic point of view.
