42 trees are obtained and the 13th is most acceptable . the results show that the evolutionary inclination of forewing and hindwing of empoascini is that the forewing evolved from these whose veins of mp “ are derived from cell r , to these whose mp “ from cell m , and the most advanced taxa include these whose 3 distal veins are derived from cell m . the hindwing are evolved from these whose cua is branched and the mp “ + cua “ is presented , to those whose cua is unbranched and mp “ + cua “ disappeared , based on the above analysis , the genera of empoascini can be divided into two groups : one group includes these whose mp “ + cua “ are present , the other consists of those whose mp “ + cua “ are disappeared 在系統發育方面，應用hennig86 ( version1 . 5 )軟件，根據中國小綠葉蟬族40個屬及外群dikraneura ，首次研究了該族的系統發育關系，根據研究結果初步提出了該族前、后翅脈的進化方向，即該族前翅翅脈呈現出mp脈源于r室，逐漸進化到mp脈源于m室，最后前翅3條端脈皆源于m室的趨勢；后翅翅脈由cua脈端部分二叉，進化到后翅cua脈端部不分叉、 mp + cua脈退化的趨勢。 |

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 . then the three - dimensional finite element models of biomimetic wings are built by choosing the suitable element types and characteristic parameters 本文基于蜻蜓真實的翅翼樣本,利用相應cad軟件分別建立了前、后翅翼的幾何結構模型,并通過選擇適當的單元類型及設定特性參數,完成三維仿蜻蜓前、后翅翼的有限元建模。 |

In this order the forewings are modified to form hard elytra or cases . 該目昆蟲的前翅發展成堅硬的鞘翅或殼。 |
