中文摘要
温稠密物质特性,包括状态方程、输运系数及X光吸收谱等,是武器物理、惯性约束核聚变等工程领域关心的重要科学问题,同时也是凝聚态物理、等离子体物理、天体物理领域的前沿科学问题。出于对高精度状态方程、输运系数研究的实际需求,以及发现新的物质相变规律和动力学响应特性的基础科学发展需要,我们将从数值模拟、理论建模、以及数据分析与挖掘等多个角度统筹出发,协同有机地研究典型聚变、裂变材料(氘氚、碳氢、氘化锂、铍、铀等)的多相物性、电子-离子能量弛豫过程以及X光吸收过程,理解和阐明其高温高压相变的物理本质,从而为最终形成温稠密物质物理性质的重现与预测能力奠定坚实的基础。本项目将发展适用于温稠密物质特性研究的物理方案及数值模拟程序;针对辐射、冲击实验加载条件,研究典型聚变、裂变材料的温稠密状态方程;开展温稠密物质离子、电子输运系数及电子-离子能量弛豫过程的理论模拟研究;温稠密物质X光吸收谱的理论模拟研究。
英文摘要
The physical properties of warm dense matters, including the equations of states, transport coefficients and X-ray absorption spectrum, are important scientific issues in the fields of weapon physics, inertial confinement fusion and other engineering fields. They are also frontier scientific issues in the fields of condensed matter physics, plasma physics and astrophysics. In order to meet the practical needs of high-precision equations of states, transport coefficients and basic scientific development of discovering new phase transition laws and dynamic response characteristics of materials, we will study typical fusion and fission materials (deuterium, hydrogen, lithium deuterium, beryllium, uranium) synergistically and organically from the perspectives of numerical simulation, theoretical modeling, data analysis and mining. To understand and clarify the physical nature of phase transition at high temperature and high pressure, such as multi-phase properties, electron-ion energy relaxation process and X-ray absorption process, so as to lay a solid foundation for reproducing and predicting the physical properties of warm dense matters. This project will develop physical schemes and numerical simulation programs suitable for the study of the characteristics of warm dense matters; Study the temperature-dense equation of state of typical fusion and fission materials under the loading conditions of radiation and shock experiments; Carry out theoretical simulation studies on ion, electron transport coefficient and electron-ion energy relaxation process of warm and dense materials; Study on theoretical simulation of X-ray absorption spectra of warm dense matters.
