单词 Miller
释义 Miller2 Cryst.|ˈmɪlə(r)|
The name of W. H. Miller (1801–80), English scientist, used attrib. with reference to the method for specifying the positions of planes in crystals that he used in his Treatise on Crystallography (1839), esp. in Miller index (index n. 9 c).
1890G. H. Williams Elem. Crystallogr. ii. 31 To change the signs of any Miller symbol is to change the plane to its parallel and therefore equivalent plane on the opposite side of the crystal.1900Moses & Parsons Elem. Mineral. i. i. 10 The Miller Indices may be obtained from Weiss's parameters by first dividing each by the common multiple of their numerators and taking the reciprocal of the result.1940Glasstone Text-bk. Physical Chem. v. 336 The fact is represented by a bar over the Miller index, e.g., (111) for a face which has intercepts a, -b and c, on the axes OX, OY and OZ respectively.1966C. R. Tottle Sci. Engin. Materials iii. 55 When a plane is to be described, the notation used is that of Miller indices. The plane is extended to cut the x, y, and z axes, and the intercepts in steps of the unit cell dimensions a, b, c are written down. The reciprocals of these intercepts are next obtained, and fractions cleared to give the smallest integers again.Ibid. 59 There are six such planes in the cell, all having the last index in the Miller notation equal to 0, since they are all parallel to the hexagonal axis.
