论文摘要
当在任何天体物理环境中建模灰尘时，一个关键要素是对灰尘材料特性的演变（尺寸分布，化学成分和结构）的反应并适应局部辐射场强度和硬度以及对气体密度和动力学的反应并适应。实现此目标的最佳方法是将尽可能多的模型参数固定在实验室数据上。在本文中，我介绍了两个示例，以说明实验室天体物理学的最新进展以及仍需要哪些实验室数据来进一步推进尘埃演化模型，这是灰尘建模中的出色问题如何被推动。
A key element when modeling dust in any astrophysical environment is a self-consistent treatment of the evolution of the dust material properties (size distribution, chemical composition and structure) as they react to and adjust to the local radiation field intensity and hardness and to the gas density and dynamics. The best way to achieve this goal is to anchore as many model parameters as possible to laboratory data. In this paper, I present two examples to illustrate how outstanding questions in dust modeling have been/are being moved forward by recent advances in laboratory astrophysics and what laboratory data are still needed to further advance dust evolution models.
