12He experimented with once again in several other metropolitan areas and succeeded with Crystal Caramels.他又在其他几个城市再次尝试,并成功制出了水晶焦糖。
结晶的形状非常细小,需要用显微镜才能看得清楚,外观上看起来是平滑、块状。常见最多的是各式玛瑙

幽灵水晶,分绿幽灵,红幽灵,白幽灵等,主要组成为绿泥石,其中绿幽灵属于珍贵品种。
One crystals of metals are delicate and malleable, even though polycrystalline metals are more challenging and more robust and tend to be more practical industrially. Most polycrystalline elements could be built into large solitary crystals just after extended warmth procedure. In past times blacksmiths would warmth a bit of metallic to really make it malleable: heat tends to make several grains develop significant by incorporating smaller sized ones. The smiths would bend the softened metallic into form and then pound it awhile; the pounding would help it become polycrystalline all over again, increasing its energy.
You will find other minerals and molecules that will type these crystal lattices. Snowflakes really are a classic illustration of a about symmetric and geometrically patterned construction from ice crystals, and gemstones of all kinds are usually crystals.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟,喜欢将它们摆在家里或办公室里,认为水晶球有灵性,能保平安,带来财运。不过天然水晶不像看起来那么晶莹剔透,它也有瑕疵,我们在选购饰品的时候要注意。此外,我们还要掌握水晶的评价依据、选购方法,这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
A further sort of crystalline carbon is predicated on a molecule with sixty carbon atoms referred to as buckminsterfullerene (C60). The molecular shape is spherical. Every carbon is bonded to a few neighbours, as in graphite, as well as spherical form is achieved check here by a mix of twelve rings with 5 sides and twenty rings with six sides. Related structures have been first visualized through the American architect R. Buckminster Fuller for geodesic domes.
