17These rings are indicative of your crystal construction of nickel and can be discussed only by invoking wavelike Attributes of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。

③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。

A basic thought in crystal constructions may be the unit mobile. It is the smallest unit of volume that permits equivalent cells to be stacked together to fill all Area. By repeating the sample on the device cell again and again in all directions, the complete crystal lattice is often produced. A cube is the simplest illustration of a device mobile. Two other illustrations are revealed in Determine 1. The main is definitely the device cell for any confront-centred cubic lattice, and the next is to get a body-centred cubic lattice. These constructions are spelled out in the next paragraphs.

Most stable components located in character exist in polycrystalline variety rather then as one crystal. They are literally made up of an incredible number of grains (smaller crystals) packed with each other to fill all House. Every individual grain has a special orientation than its neighbours. Despite the fact that extended-selection purchase exists in just one grain, in the boundary among grains, the ordering modifications direction. A typical piece of iron or copper (Cu) is polycrystalline.

Fig. 4: Constructing blocks with unique shapes and floor chemistries immediate the development of distinctive crystal symmetries.

They're going to finally come up with a nice tiny uniform cluster of atoms, This can be the whole process of growing crystals. The more they will come jointly, the greater of a formation might be visible towards the naked eye. Researchers can ascertain what mineral They can be looking at by how the crystals type.

Increase to phrase checklist Include to word list [ C/U ] clear rock that looks like ice, or simply a bit of it

There is a comparable directive about crystal glass which differentiates between entire lead crystal, lead crystal and crystal.

crystal The newly crystallized quartz here grains are characterised by elongate crystals oriented oblique to the shear band margins, defining a typical grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology while in the significant w region functions as being the proverbial ' scratch-on-theglass ' wanted in the natural and organic chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter among the the individual crystals may well mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene types neutral to pale brown, subhedral to anhedral crystals, occasionally that contains inclusions of plagioclase microlaths and opaque phases.

用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。

The arrangement of the atom’s electrons establishes its chemical properties. The Homes of solids are usually predictable within the Houses in their constituent atoms and molecules, and different shell constructions of atoms are as a result chargeable for the range of solids.
