The proposed research concerns the role of water and hydroxide in nominally anhydrous materials. The focus of the study will be on determining the "sites" of these hydrous components in the host phase, on correlation of species type and concentration with properties of the host phase, and on elucidating changes in these species among various geologic environments. This will be accomplished through a program of spectroscopic investigations and computer simulations of both natural and laboratory- synthesized silicate and oxide phases. Results of the research should increase our understanding of the manner in which these trace "hydrous" components influence properties such as mechanical strength, optical behavior, dielectric constants, and response to ionizing radiation of the host phase.

这项拟议的研究涉及水和氢氧化物在名义上无水材料中的作用。研究的重点将放在确定这些含水组分在宿主相中的“位置”，物种类型和浓度与宿主相性质的相关性，以及阐明这些物种在不同地质环境中的变化。这将通过对天然和实验室合成的硅酸盐和氧化物相进行光谱研究和计算机模拟的计划来实现。研究结果将增加我们对这些痕量“含水”组分影响性质的方式的理解，如机械强度、光学行为、介电常数和对主体相的电离辐射的响应。
