This research program consists of several projects with a common theme, understanding the chemistry, dynamics, structures, and electronic properties of condensed materials under high pressures and, often, extremes of temperature. The research centers on five problem areas: 1. Melting and Other Phase Equilibria of Simple Solids and Solid Mixtures at High Pressures 2. A Search for Nitrogen Metal at Room Temperature 3. Unsaturated Carbon Compounds at Very High Static Pressures 4. Shock-Decomposition Chemistry of Benzene and Electronic Spectra from and behind Shock Fronts 5. X-Ray Diffraction under Extreme Conditions The emphasis is experimental. However, many of the systems they study are relatively simple in the sense that their properties can be modeled by theorists. They attempt to determine how these materials behave at high pressures with sufficient precision to test the accuracy of these models and, thereby, to contribute to improving their understanding of how materials respond to high stresses on the molecular level. //

该研究计划由几个项目组成， 主题，理解化学，动力学，结构， 高压下凝聚态材料的电子性质 而且经常是极端的温度。 研究的中心是 五个问题领域： 1. 简单固体和固体的熔化及其它相平衡 高压混合物 2. 室温下金属氮的探索 3. 极高静压下的不饱和碳化合物 4. 苯与电子的冲击分解化学 冲击波阵面及其后面的谱 5. 极端条件下的X射线衍射 重点是实验性的。 然而，许多系统， 研究相对简单，因为它们的性质 可以被理论家们模拟出来。 他们试图确定这些 材料在高压下具有足够的精度， 测试这些模型的准确性，从而有助于 提高他们对材料如何响应高 分子水平上的压力。 //
