查询词典 elytra

The study investigates fabrication of quasi-structure with elytra from Buprestid, optical analysis of microstructure is also discussed.

本研究针对吉丁虫翅鞘微结构的仿造，并对仿造之微结构进行光学分析。

Six species of elytra of Buprestid are chosen to investigate various colors on the surface and cross-section of elytra. Optical microscopy and scanning electron microscopy are also performed to observed microstructure and surface topography of elytra.

先研究六种选定的吉丁虫翅鞘，分别对各个不同颜色的翅鞘做表面及剖面结构的探讨与成分分析，以光学显微镜及扫描式电子显微镜分别观察翅鞘的色层分布及微结构。

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。

It is interesting that great differences have been discovered for the external surface design techniques of the four kind of insect elytra.

有趣的是，四种鞘翅的表面设计，则呈现了较大的差异性。

This character is similar to aquatic firefly L. substriata though the end of elytra of L.

这一特征与水栖萤火虫条背萤类似，但条背萤的鞘翅末端具一黑斑。

The main component of elytra are Carbon and Oxygen analyzed by ESCA, the ratio is 4:1 approximately.

经成分分析得知主要成分为碳及氧，所含比例大约是4：1。

The shape and size of trabeculae, which form the internal bridges between the upper and lower surfaces of the elytra, depend on the species of beetles.

不过，和以往的认识不同的是，两种甲虫前翅的小柱具有类似的结构，它们均为非中空的实柱，并由中心部和环状的几丁质纤维层构成。

This dissertation is the first in its series in which at least three ones can work, the next one will work on the structure/property relations to understand and reveal the mechanism of the insect elytra as natural composites, and based on the above two parts of work, the last will design and fabricate commercial products of biomimetical composites and composite structures, or form new design regulations.

第二部分工作为通过建立力学模型认识和发现自然复合材料昆虫鞘翅的力学机理的结构/性能关系研究，第三部分工作为基于上述两部分工作制造达到商用程度的仿生复合材料及其结构或形成新的设计规范。

Also cavity in the elytra was found, which are supported by pier formed pillars formed by integument sinking for supporting and reducing weight.

膜翅的背腹壁之间也具有内腔和皮细胞，并充满油脂腺(经分析是棕脂肪细胞腺)及其分泌物。

For more investigation on the linkage-structure of elytra, the opening-closing process of elytra is recorded. Besides, the strength of linkage between the elytra was measured, and Protaetia brevitarsis has the strongest coupling force. At last, the elytra linkage-structure model was analysed by simulating its movement and analyzing its structure using Pro/Engineer, it is proved that the structure is especial and efficient.

本文为了更好地研究此鞘翅间联接锁定机构，对甲虫鞘翅的瞬间开合过程进行了拍摄；还对此机构的联接强度进行了测定，发现甲虫鞘翅间联接力都要远远大于甲壳虫它自身的重量，其中白星花金龟的联接强度最高；最后通过几何建模，对联接机构进行运动模拟仿真及结构有限元分析，证明了甲虫鞘翅联接机构的特殊性和高效性。
