A good is crystalline if it has lengthy-selection order. After the positions of an atom and its neighbours are recognised at one particular place, the location of every atom is understood precisely throughout the crystal. Most liquids absence extensive-range buy, Even though numerous have quick-array purchase. Limited assortment is outlined as the first- or second-closest neighbours of the atom. In several liquids the main-neighbour atoms are arranged in a similar composition as while in the corresponding stable period.
①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。
If you wish to see how crystals are formed, you can do a little task in your quite very own kitchen and find out the development with the crystals come about using your individual eyes . This can be carried out by Placing a little level of desk salt into some typical faucet h2o, hold out 24 several hours, and you may see pleasant cubed formations. This occurs as the h2o is evaporating, which triggers the atoms that make up the salt (the mineral) along with the water to return nearer collectively.
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。
30Three times went past, and I was astonished to view it again: many of the openings have been sewed up by thin and white thread they usually appeared such as ice crystal on Winter season's branches inside the north.
26Some of the finest drinking Eyeglasses are produced from guide crystal.一些最精致的酒杯是用铅晶质玻璃制成的。《柯林斯英汉双解大词典》
One of the binary crystals, the easiest constructions to visualise are those with equal quantities of the two sorts of atoms. The structure of sodium chloride is predicated on the cube. To construct the lattice, the sodium and chlorine atoms are placed on alternate corners of the cube, as well as the composition is recurring (Figure 3B).
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
One crystals of metals are smooth and malleable, while polycrystalline metals are more difficult and stronger and tend to be more practical industrially. Most polycrystalline elements is usually made into massive one crystals following extended heat therapy. Up to now blacksmiths would warmth a piece of metallic to make it malleable: heat helps make some grains mature significant by incorporating smaller ones. The smiths would bend the softened metallic into shape and then pound it awhile; the pounding would make it polycrystalline once again, increasing its strength.
国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
This Evaluation chronicles in excess of two decades of exploration into developing a genetic code for crystal engineering. Rather then directing biological procedures, this code works by using artificial sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each individual facet of the resultant structures can be systematically managed. Within this conceptual framework, the structural and useful innovations are explained in an effort to determine the current level of sophistication also website to predict upcoming Instructions from the System.
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
