摘要：Fundamental in building any materials database is the capability to describe the materials whose data are contained therein accurately. While many systems exist for describing traditional materials, such as metals, polymers, ceramics, and others, the evolving field of nanotechnology presents new challenges. In this paper, we define the goals of a materials description system and the information categories used to describe traditional materials. We then discuss the challenges presented by materials on the nanoscale and suggest ways of overcoming those challenges.
