The UV-visible spectra of oxidized and reduced F28Y and F106Y were in agreement with the wild NGB, but the oxidized F28Y＇s Sorer band had a 2 nm blue shift, which suggested that the two mutants still remain hexa-coordinated form.

氧化型和还原型F28Y及F106Y的紫外-可见吸收光谱与野生型相似，仅氧化型F28Y的Soret带有2nm的蓝移，说明这两种突变体蛋白仍保持六配位形式。F28Y的荧光最大发射峰明显红移（340nm→347nm），表明其荧光基团更加暴露于极性环境中。

The low temperature buffer layer was epitaxied on the Si substrate at the temperature of 300°C. Non-finite ZnO was grown on the substrate due to the low temperature at which the Zn and O atoms is easy to be absorbed on the substrata, which could relaxed effectively the effects of the lattice mismatch between the substrate and ZnO thin films on the quality of the ZnO films and could reduce the formation of distortion and defects.

在 300℃温度下生长了一层 ZnO 薄膜，由于生长温度较低 Zn、O 原子容易被吸附到衬底的表面导致非定形的 ZnO 的生长，有效减缓了衬底与 ZnO 之间的晶格失配带来的影响，降低了失配位错和缺陷的产生。

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。

As known, Mo-O compounds are prone to cluster structure. For compound 5, Mo〓O〓 unit is a loop-structure, two HPO〓 tetrahedrons are c oordinated to loop-structure from up and down, respectively.

在钼-氧化合物中，我们知道，钼-氧化合物易于形成笼状结构，在化合物5中，Mo〓O〓形成一个环状结构，两个HPO〓分别配位在环的上下，形成一个&飞碟&状的结构。
