A chainlike molecule made up of smaller molecular units. 2. A material exists in two or more crystal structures. After changing from one crystal structure into another, the material can reverse the phenomenon and return to its previous crystal structure. 3. A point defect is produced by the presence of an extra atom in a void, the space between normal lattice positions. 4. A solid solution in which the impurity atoms take up sites in the lattice structure that are normally unfilled or unoccupied by the pure (solvent) atoms. 5. A term referring to a variety of liquids and solids that have the ability at a predetermined condition to sense stresses and respond to alter their properties. 6. An ion with a positive charge. 7. One basic form of solid possesses an ordered, three-dimensional, geometric arrangement that repeats itself. 8. The degree to which an atom attracts electrons. 9. The forces that produce secondary (or weak) bonds. 10. The materials have the structures in which the orderly arrangement of atoms extends throughout PDF 文件使用 "pdfFactory Pro" 试用版本创建 www.fineprint.com.cn
