轴性、光性：一轴晶正光性。正交偏光下所看到的一轴晶干涉图是独特的，其黑十字臂未达中心，形成中空的图案，俗称牛眼干涉图。中心部分通常为淡绿色或淡粉色。
12He attempted once again in many other cities 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。
A crystal composition focuses on how the atoms are arranged In the crystal. Having said that, crystallographers have an interest in the overall condition and dimensions of your crystal as well as its external characteristics. To accomplish this, they have to understand about the crystal process.
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。

Fig. one: Schematic of crystal development from creating blocks composed of a particle Main as well as a shell of DNA ligands connected for the particle floor.
This Evaluation chronicles in excess of two decades of exploration into making a genetic code for crystal engineering. As an alternative to directing Organic procedures, this code uses synthetic sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which almost just about every element of the resultant buildings is often systematically controlled. Inside this conceptual framework, the structural and useful advances are explained in order to outline the present amount of sophistication and to forecast long term directions of the System.
Tetragonal �?Characterized by 3 mutually perpendicular axes, two of which are equal in size, when the third is more time or shorter and perpendicular to one other two.
