She walked the hills like Dorothy Wordsworth and, like William Wordsworth, paddled a boat among the reflections of the stars, the dragonflies "coming up from the depths to meet the real dragonflies as they skim down onto the surface, which is the skin between the two worlds of air and water".

The modeling and analysis method, as well as the conclusions are helpful to the design, fabrication and application of FMAV. Based on the real structure of the forewing and hindwing of dragonfly, the plane geometric models of biomimetic wings are created using some CAD software.

本文基于蜻蜓真实的翅翼样本，利用相应CAD软件分别建立了前、后翅翼的几何结构模型，并通过选择适当的单元类型及设定特性参数，完成三维仿蜻蜓前、后翅翼的有限元建模。

"All of these symptoms, and the underlying processes behind these symptoms that we're seeing in these dragonflies, are pretty much identical to what you see in mammalian metabolic syndrome and obesity," said Marden."We're seeing it all relate back to this non-inasie protozoan in the gut."

在蜻蜓观察到的所有症状及症状背后的代谢过程与哺乳动物的代谢综合征、肥胖极其相似" Marden说，"我们认为蜻蜓的这些症状与非侵入性的消化道原虫有关。

Analyses of stomach contents showed that, for adult bullfrogs, the most important prey items overall were Decapoda, Coleoptera, Odonata, Mesogastropoda, Raniformes, and Cypriniformes; while for juvenile bullfrogs, they were Decapoda, Coleoptera, Cypriniformes, Odonata, Orthoptera, Hymenoptera, Lepidoptera larvae, Mesogastropoda, and Raniformes. Moreover, prey size and diet volume increased with the body size of both adult and juvenile bullfrogs. The diet composition of primary preys of bullfrogs was significantly different among different islands.

食性分析结果表明：(1)按食物体积计算，成年牛蛙以十足目、鞘翅目、蜻蜓目、中腹足目、蛙形目和鲤形目为主要食物，亚成体牛蛙以十足目、鞘翅目、鲤形目、蜻蜓目、直翅目、膜翅目、鳞翅目幼虫、中腹足目和蛙形目为主要食物；成体和亚成体牛蛙胃中食物的平均大小均随其体长增加而增大；(2)不同岛屿上的牛蛙在主要食物类型构成上存在差异。

Firstly, the high resolution pictures of dragonfly wings from sample tests were studied thoroughly, and the unique feature of the reticulate vein distribution and the variation of the vein sizes and the grid shapes in different zones were figured out;then several computational models based on a dragonfly wing were established by using ANSYS, and beam 189 and shell 93 elements were used respectively in modeling of the veins and the membrane so as to ensure the compatibility between the veins and the membrane at a deformed state;these models subject to uniform loading cases were analyzed respectively so as to explore the unique performances of the wing structure, furthermore, through eigenvalue spectrum analyses of these models, the special role of the pterostigma in eliminating or suppressing the wing quivering effect was also evaluated.

首先，对实验中获取的高清晰度的蜻蜓翅膀数码图片进行了细致地分析，找出了翅膀网状翅脉结构中翅脉的分布规律与尺寸变化、网格形状的差异及不同形状网格的分布等独特的结构特征；再利用ANSYS建立蜻蜒翅膀网状翅脉结构模型，采用三节点等参数梁元beam189模拟翅脉和八节点等参数曲壳单元shell93模拟翅膜，以满足翅脉和翅膜间的变形协调性要求；通过非线性数值分析，探索了蜻蜓翅膀网状翅脉结构在均布荷载作用下所具有的独特的结构性能；通过模态分析，揭示了翅膀前缘靠近翼尖附近的翅痣在翅膀消震减振中所发挥的作用。

Beautiful green dragonfly, fly it lightly, the sharp reversal of the time, shoot kissed, you still remember how you, with love and curiosity, gazed at this lovely little wizard, I should be this beautiful Green dragonfly wear on your head, so she always轻吻with your hair, as I kiss your body falls, and numerous green diamond crystal and beautiful, elegant shape, the dragonfly's body was light most.

美丽的绿蜻蜓，它翩跹飞舞，急转之时，吻了一下枝梢，您还记得，您怀着何等的爱意和好奇，凝视着这只可爱的小精灵，今天我要把这个美丽的绿蜻蜓戴在你的头上，让她时刻轻吻着你的秀发，就像我的吻落在你的身上，无数的绿色水钻晶莹而美丽，精致的造型，把蜻蜓轻盈的身体表现得淋漓尽致。
