The principal investigator will make a series of experimental measurements relevant to multicomponent diffusion in anhydrous silicate liquids. The aims are to document the diffusive coupling of melt components, to provide a database for diffusion models, and to attempt to determine melt species. The results will be used to model crystal growth from magmatic liquids and to construct more physically realistic configurational entropy models for such liquids.

首席研究员将进行一系列与无水硅酸盐液体中多组分扩散相关的实验测量。目的是记录熔体成分的扩散耦合，为扩散模型提供数据库，并尝试确定熔体种类。结果将用于模拟岩浆液体的晶体生长，并为此类液体构建更物理真实的构型熵模型。
