The Definitive Guide to Crystal
天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。A fundamental idea in crystal buildings may be the unit mobile. It is the smallest device of volume that allows equivalent cells for being organized collectively to occupy all offered House. The geometrical basis of all crystals would be the lattice. A lattice is often seen as a regular and infinite arrangement of points or atoms, where Every level or atom has an identical encompassing environment.
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。

Find out how The form of the crystals ascertain the several minerals into familiesMinerals crystallize according to amongst seven motifs, often known as crystal programs.
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
13Nearly all pcs consist of a quartz-crystal clock to regulate their operation.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。

地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
The arrangement of the atom’s electrons determines its chemical Houses. The Qualities of solids are often predictable with the Houses of their constituent atoms and molecules, and the various shell buildings of atoms are for that reason accountable for the variety of solids.
crystal, any strong materials during which the element atoms are arranged in the definite pattern and whose area regularity displays its internal symmetry.
Binary crystals are found in several structures. Some pairs of aspects type more than one construction. At area temperature, Crystal cadmium sulfide may possibly crystallize possibly in the zinc blende or wurtzite structure. Alumina also has two probable buildings at space temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinctive constructions at various temperatures. Among the most complicated crystals are These of silicon dioxide (SiO2), that has seven unique structures at numerous temperatures and pressures; the commonest of these constructions is quartz.
