研究成果

地球在其形成演化过程中，如何获取挥发性元素(如H、C、N等)，以建立生命宜居的基本条件，一直是科学界争论的焦点。由于缺失极端温压条件下的分配数据，人们无法全面了解挥发性元素在地球内部的丰度与圈层之间的分布，也难以揭示它们的起源与演化历史。

为了解决上述研究瓶颈，我们建立了具有广泛适用性、元素分配系数的第一性原理计算方法(Yuan et al., 2024, JGR; 2023, EPSL; 2022, GRL; 2021, JGR; 2020, JGR; 2020, GRL)，其主要价值在于两方面：

(1) 该方法能够在极端地质温压条件下对各种元素的分配行为进行量化研究，为约束地球内部挥发元素的丰度和分布提供了一种系统的有效途径；

(2) 该方法以量子力学、分子动力学为理论基础，为理解元素的物理化学行为提供了电子、原子等微观层面的重要信息。

已发表国际期刊论文15篇，含第一作者论文8篇 (包括1篇EPSL、3篇JGR、3篇GRL、1篇PCM，其中自然指数期刊论文7篇)。
