| 单词 | laue pattern |
| 释义 | > as lemmasLaue pattern Used attributively with reference to a method of X-ray diffraction developed by Laue in which a narrow parallel beam of polychromatic X-radiation is directed at a thin crystal and the resulting diffraction pattern is recorded on a photographic film placed either in front of the crystal (with a hole for the passage of the incident beam) or beyond it; as Laue method, Laue pattern, Laue photograph.

H. Bragg & W. L. Bragg X Rays & Crystal Struct. xii. 208 Each spot in a Laue photograph represents the reflection of the X-rays by a certain plane (hkl) of the crystal structure. 1935 Jrnl. Chem. Physics 3 421/1 Oscillation and Laue photographs were prepared with crystals of lepidocrocite from Eiserfeld, Westerfald, Germany. 1940 Nature 7 Sept. 332/2 The diffuse spot pattern changes much more slowly than the Laue pattern on successive photographs. 1955 E. S. Gould Inorg. Reactions & Struct. xx. 310 The Laue method, employing polychromatic radiation, is no longer important as a tool for structure determinations. Laue photographs are used chiefly for lining up crystals preliminary to examination by filtered radiation, for partial indications of symmetry, and for indicating imperfections and deformations in crystals. 1973 Soviet Physics: Crystallogr. XVIII. 320/1 The symmetry of the Laue pattern allowed the mineral to belong to the hexagonal system. < as lemmas |
