查询词典 elytron

This thesis focuses on beetle Cybister tripunctatus in addition to some other species of beetles and studied the elytron's micro-structure. We found that there are many concaves、hollows and holes on its structure; the configuration of this material is compound samdwich; the linkage-structure between elytra adopts the concave-protuberant mesh joint with some bristle.

本文以东方龙虱为重点研究对象，并综合了四个科的十个物种，通过对甲虫鞘翅微结构的观测，发现东方龙虱鞘翅表面遍布着很小的凹坑；从其鞘翅断面来看，内部存在着许多空腔和孔道结构，而且甲虫鞘翅是复合层状结构；对鞘翅间联接处研究发现，联接机构采用了凹凸啮合结构，在局部区域存在微小毛刺和突起结构来增加摩擦接触。

During the millions of years'evolution, beetle's elytron has developed the special structure and function to adapt their survival environment.

经过上百万年的生物进化，甲壳虫发展出与其生存环境相适应的具有特殊构造和功能的鞘翅。

In conclusion, the control mechanism of beetle's elytron is quite complicated, and all the results of this thesis set up a basis for the further bionic design of structure and its optimization in the field of aviation and spaceflight.

总之，甲虫鞘翅间联接锁定机构的控制机理是相当复杂的，而这些研究成果对航空航天领域中的联接机构结构设计与优化有一定的仿生依据和重要价值。

After testing the mechanical property of elytron with nanoindentation, the experiment result shows that values of Cybister tripunctatus's elytron chitin are higher than the average values, and the mechanical property of different testing areas are dissimilar.

在对多种甲虫鞘翅运用纳米压痕仪进行力学性能测试后，发现东方龙虱鞘翅壳质层的力学性能数值要大于总体的平均值，而且同一甲虫鞘翅的不同测试区的力学性能也存在差异。

The genetic distance a mong different splash types of H.axyridis was 0.0021 to 0.0328 The aver age gene tic distance was 0.0193 The molecular phylogenetic tree suggested that the me mb ers with the same elytron color were grouped together with high bootstrap confid ence values, showing low diversity among the populations. H. axyridis ab. luna t a Hem and H.axyridis var. spectabilis Fald were most closely related. H.ax yridis var. axyridis Pallas was a primordial population of coccinellidae, which wa s differentiated earlier than the other populations.

分子系统树显示：各类群间遗传分化很小，鞘翅颜色相同的瓢虫均已较高的置信值聚在一起；双月斑变型和显明变种亲缘关系最近，重名变种为原始类群，分化较早，与其它12种不同色斑异色瓢虫亲缘关系较远。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
