rhombohedral

1 A stereographic projection of a rhombohedral crystal is given in fig.

2 As in the other rhombohedral carbonates, the crystals possess perfect cleavages parallel to the faces of the rhombohedron.

3 By some authors these two divisions are treated as separate systems; or again the rhombohedral forms may be considered as hemihedral developments 580 of the hexagonal.

4 "Rather," it has an elongated rhombohedral structure.

相反，它有一种拉长的斜方六面体结构。

5 Another of these crystals, doubly terminated, measures 2½ inches by 11/12 of an inch, and is filled with large rhombohedral cavities, which formerly contained dolomite.

6 GRAPHITE, a mineral species consisting of the element carbon crystallized in the rhombohedral system.

7 The crystals measure up to a yard across, and are rhombohedral or scalenohedral in habit; their faces are usually dull and corroded or coated with stilbite.

8 The X ray diffraction (XRD) results showed that the rhombohedral phase fraction of natural graphite increased after being coated.

射线分析表明，改性后该石墨晶体中三方石墨的含量增高。

9 There are two forms occurring there, the most abundant of which is the rhombohedral, after Fig.

10 It crystallises in colorless rhombohedral with a relative density of 1.95.

高氯酸铵是一种无色菱形晶体,相对密度1.95.

11 It is commonly massive, but occurs also in rhombohedral crystals.

12 Nothing here but illimitable mysteries, Baffling unknowledgeableness, Fathomless, fainting from square to square, Oblongs and nosey triangles, ever so nosey, Shapes rhomboidal, perchance rhombohedral—who knows?

13 It was not common carbonate of lime, for the crystals were rhombohedral and did not show the cleavage of calcite.

14 Those with a triad axis are grouped together in the rhombohedral or trigonal division, and those with a hexad axis in the hexagonal division.

15 After the electron beam had been shifted away, the rhombohedral structure was restored.

电子束移开后, 又恢复到原来的菱面体结构.

16 Chalybite crystallizes in the rhombohedral system and is isomorphous with calcite; like this it possesses perfect cleavages parallel to the faces of the primitive rhombohedron, the angles between which are 73� 0′.

17 After doping, the LSCF phase remained rhombohedral structure.

掺杂后的LSCF仍保持菱方结构；

18 Crystals of calcite are extremely varied in form, but, as a rule, they may be referred to four distinct habits, namely: rhombohedral, prismatic, scalenohedral and tabular.

19 The habit of the crystals may be rhombohedral, pyramidal or tabular, rarely prismatic.

20 It is rhombohedral in its crystallization, and thus distinguished from aragonite.
