翅

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。

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。

Elytrum carves a spot close, shoulder apophysis.

鞘翅刻点细密，肩角隆起。

马铃薯甲虫的鞘翅

Fruit elliptic, apex neither winged nor emarginate or retuse; ovules or seeds 4-8-10

果椭圆形，先端既不具翅也不微缺的或微凹；胚珠或种子4-8(-10) 5 T。

And when his wings enfold you yield to him

当他的翼翅拥抱你们的时候，就屈服于他吧

He fell heavily to the ground and Ulysses vaunted over him saying, O Socus, son of Hippasus tamer of horses, death has been too quick for you and you have not escaped him: poor wretch, not even in death shall your father and mother close your eyes, but the ravening vultures shall enshroud you with the flapping of their dark wings and devour you.

他随即倒地，轰然一声；神勇的俄底修斯开口吹嚷，喊道：索科斯，聪明的驯马者希帕索斯的儿子，死亡追上并放倒了你；你躲不过它的追击。可怜的东西，你的父亲和尊贵的母亲将不能为你合上眼睛；利爪的兀鹫会扒开你的皮肉，双翅击打着你的躯体！

Floral tubes smooth walled or 6-12(-14)-ribbed; ribs broad and flat or sharply ridged, without undulate wings; floral tubes glabrous or pubescent; epicalyx present or absent

花被管壁平滑或6-12(-14)棱；锐棱宽和平的或被使成脊状，没有波状的翅；花被管无毛或被短柔毛；副萼存在或无 4

The wing is a flattened evagination of the dorsal body wall.

翅是昆虫背板的片状翻出物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
