六方晶系

To be more exact; to be more precise

在六方密排晶格中，滑移系受到较多的限制。

Two kinds of stable decagonal quasicrystals and 16 approximants have been found in Al-Cr- alloys by means of selected-area electron diffraction, high resolution electron microscopy image and X-ray single crystalline diffraction.

用选区电子衍射和高分辨像等手段，确定了Al-Cr-合金系中的16个准晶近似相，其中的7个准晶近似相为新相，它们是：六方τ相，六方μ′相和正交ε相，以及周期为3.72nm的正交(2/1，2/1)，(1/1，3/2)，(2/1，3/2)相和α=2.29nm，c=3.71nm，β=108°的单斜相。

In alkali borosilicate system, hexagonal CdS was the main crystalphase, co-precipitated with a little cubic CdS.

碱系中，以六方型CdS为主要晶相的纳米晶体，伴有少量立方型CdS析出。

The results showed that the catalyst was hexagonal crystalline rod-shaped nanoparticle α-Fe2O3 with major axis of about (300-500) nm and minor axis of about (20-40) nm.

结果表明，制备的光催化剂为六方晶系的纳米棒状α-FeZO3，其长轴约为(300~500) nm，短轴约为(20~40) nm。

Although CdS and NiSe belonged to the same crystal system, they had a great difference in the morphology of products produced in ethylenediamine by a solvothermal process. By making a crytallographic comparison between CdS and NiSe, I thought that fourcoordinated crystals were more prone to grow one-dimensionally in the stacking direction of tetrahedrons. This hypothesis could also be embodied in many examples.

硫化镉和硒化镍的晶体结构都为六方晶系，但在以乙二胺为溶剂的溶剂热条件下合成出的产物形貌有很大的差别，我们通过对两类晶体结构的结晶学比较，我们认为4配位的晶体更趋向于生成一维纳米材料，并提出生长方向即为四面体堆积方向，这一假设也能得到许多例子的证实。

It was showed that the PELA polymer chain was included inside the molecular tube formed by multiple α-CD molecules, which aligned into close-packed hexagonal crystalline structures.

结果表明：PELA分子链被包结在α-CD分子形成的管道中，α-CD分子管道并排紧密排列，形成六方晶系的晶体。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
