STRUCTURE: Titanium and composites used extensively, with particular emphasis on corrosion resistance; fully articulated three-blade coaxial contrarotatmg rotors have all-composites blades with carbon fibre and glass fibre main spars, pockets (13 per blade) of Kevlar-type material, and filler similar to Nomex; blades have non-symmetrical aerofoil section; each has ground-adjustable tab; each lower blade carries adjustable vibration damper, comprising two dependent weights, on root section, with further vibration dampers in fuselage; tip light on each upper blade; blades fold manually outboard of all control mechanisms, to folded width within track of main landing gear; rotor hub is 50% titaniuin/50% steel; rotor brake standard; all-metal fuselage; composites tailcone; fixed incidence tailplane, elevators, fins and rudders have aluminium alloy structure, composites skins; fins toe inward approximately 25°; fixed leading-edge slat on each fin prevents airflow over fin stalling in crosswinds or at high yaw angles.

结构：钛和复合材料广泛使用，耐腐蚀性能与特别强调，充分阐明三叶片转子同轴contrarotatmg有碳纤维和玻璃纤维的主要棒材全复合材料桨叶，口袋（每刀片13）凯夫拉型材料，类似的Nomex纤维填料；叶片非对称机翼部分，每有地面可调选项卡，每降低叶片振动阻尼器进行调节，包括两部分依赖重根，在机身进一步减振装置；小费每个刀片上轻；刀片倍手动舷外所有控制机制，折叠宽度内的主起落架的轨道；转子中心为50％titaniuin/50％钢；转子制动标准；全金属机身，复合材料tailcone，固定发生机尾，电梯，蛙鞋和方向舵的铝合金结构，复合材料的皮肤；鳍鳍在每个脚趾向内约25 °；固定领先的板式翅片防止了侧风或气流停滞在高偏航角度。

The experimental result shows, Morpho butterfly's wing micro-structure forms the reflecting rate higher than the reflecting rate of other butterflies, so regard Morpho butterfly as and transfer to the micro-structure of printing, is observed by SEM and transfered to the vein micro-structure printed, demonstrate the same array scale as Morpho butterfly and carinate fin slice, small in more quantity than Morpho butterfly in the slight branch form structure, but metal micro-structure of color and luster printed off to transfer to raise reflect, it is it print off by AFM array carinate fin of alternate size nearly the width of 1.5μm to transfer to measure.

实验以高解析光学显微镜及紫外光/可见光光谱仪分析虎斑蝶、碧翠凤蝶、锯粉蝶、摩浮尔蝶蝶翼表面的光学反射、穿透与吸收特性，实验结果显示，转印的Morpho蝶翼微结构与真实摩浮尔蝶反射率较相近，故将Morpho蝶作为转印微结构，由SEM观察转印的翅脉微结构，呈现出与Morpho蝶相同的阵列鳞片与脊状的鳍片，虽细微的树枝状结构少，但转印出的微结构溅镀20nm的金属膜提高反射率，而由AFM检测转印出阵列脊状的鳍片间隔尺寸约为1.5μm的宽度。

Hoxall genes from 16 vertebrates were analyzed, containing 10 cloned Hoxall genes mentioned above and 6 Hoxall genes from GenBank, Homo sapiens, Mus musculus, Bos taurus, Polyodon spathula, Heterodontus francisci, and Oryzias latipes, in representatives of the three major gnathostome lineages: cartilaginous fish, ray-finned fish and lobe-finned fish.
