看颜色:即使在同一种类的水晶中,它的不同部位的纹理、色泽也各式各有千秋。属于单色的,要色度均匀;在同一块水晶上有深浅的,则要求其色调纹路美观大方。
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。
10This will be the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
We have penned about over 300 stones in the mineral kingdom! Read about each stone's one of a kind origin, record, and energies below.
How Crystals Variety The process of forming a crystal is called crystallization. Crystallization usually takes place any time a strong crystal grows from the liquid or Alternative.
Lattices could possibly have a single lattice place for each mobile or multiple, yielding a complete of 14 Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the 3-dimensional array produced by a list of discrete details.
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
损伤是指水晶由于加工或不小心摔掉、碰撞等原因,人为造成的损坏。它可以是破口,也可以是凹坑等。
One of the binary crystals, the best constructions to visualize are These with equal numbers of The 2 sorts of atoms. The construction of sodium chloride is based with a dice. To build the lattice, the sodium and chlorine atoms are put on alternate corners of a cube, plus the framework is repeated (Figure 3B).
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
⑥、丝印:水晶表面附有不同的色料进行效果处理,颜色层面较厚,着力后方可脱落。
You'll find just a few diverse device-mobile styles, so numerous crystals share one device-mobile form. An important attribute of a device mobile is the volume of atoms it is made up of. The entire variety of atoms in the whole crystal is definitely the number in Every single cell multiplied by the amount of device cells. Copper and aluminum (Al) Every have 1 atom for every device cell, whilst zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms per unit mobile, but usually there are some exceptions. Crystals of polymers, as an example, have A large number of atoms in each device cell.
⑨、喷砂:立体感弱,较平整,无凹凸感,机器雕刻文字、图形等后进行效果处理。成本低制作快。
crystal Alteration is variable: absent in lots of crystals, in Other folks manufacturing dense sericite aggregates which may clearly show some recrystallization consequences to supply coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. Within the Cambridge English Corpus In addition, haloarchaeal cells were embedded inside salt crystals under laboratory circumstances and subsequently analysed by light microscopy. With the Cambridge English Corpus The white clouds (normally sparse) were also commonly thought to be becoming made up of tiny crystals of h2o ice, relatively like cirrus inside our ambiance. In the Cambridge English Corpus These are found in evaporite salt lakes and will be trapped in salt crystals for the duration of evaporation. From the Cambridge English Corpus Thus, the cells (organelles and membranes) are destroyed mechanically by ice crystals, resulting in Loss of life as a result of cell lysis. In the Cambridge English Corpus The crystals were being used in the initial or second orders of reflection. With the Cambridge English Corpus In our 8xperiments, the crystals had been cubes by using a base space of 8 e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive more info doped molecular crystals : influence of temperature and pressure.
