利用该作用势得出了六配位数碱卤化物晶体的性质，并描述了CdSe的三种晶体结构：纤锌矿、闪锌矿和岩盐矿型结构。

Therefore, the structure could be stable. However, the structure was changed to amorphous when the strain level was over 15%. At the same time, the binding energy increased rapidly and the structure stability was reduced. During the deformation process, both the bond angle and bond length were significantly affected by the strain level.

这表明Ni纳米线的径向很软，结构之间几乎没有能量转换，且其稳定性基本不变；当压缩程度大于15%时，Ni纳米线结构变为无定形结构，它的结合能变大，且变化很快，表明其稳定性降低；压缩程度对Ni纳米线键角和键长的分布有着很大的影响。

The replica material used in this study is Polydimethylsiloxane. The enlargement of replica compared to original size is 2.34%. Since PDMS is transparent, a layer of metal should be sputtered on its surface to measure optical characteristic, however the accuracy will be affected by the metal coated. The result assumes that Sternocera aquisignata, Chrysochroa rajah and Catoxantha opulenta may have one-dimensional photonic crystal structure. The fabrication of quasi-structure with elytra from Buprestid can promote the applications in the field of photonic structure and optical components.

经PDMS翻印的结果，最小仅增加原始尺寸的2.34%，翻印结果良好，但因翻印结果需镀上一层材料，使得镀上的材料严重影响结构的反射率，造成结构不同反射率也类似的情形，将结构刻画在不需镀金的材料上，将可防止镀上材料影响反射率的问题，并将所制成之结构用於防伪、光子结构研究和光学元件上。
