蜻蜓

Condensable children waited in the grass can not make it by hand to prevent the dragonfly catches behind.

小孩子屏息凝气也能在草丛间用手把那不作防范的蜻蜓抓个正着。

Result The results show that A+T contents of CO Ⅱ genes of Libellulidae are lower (68.6%) in Insecta, which proves Odonata is an original group. Every sequence includes 2 Cys, which differs from the other groups of Insecta. Do not agree with the view of raising Macrominae into Macromidae. Agree with the views of putting both Aeshnidae and Cordulegastridae into Aeshnidea, and raising Gomphidae into a superfamily. Order of the evolution relationship of 5 families is: Gomphidae→Cordulegastridae→Aeshnidae→Corduliidae→Libellulidae.

结果］CO Ⅱ的A+T含量较低(68.6%)，说明蜻蜓目是一比较原始的类群；每条序列均含有2个半胱氨酸，这一点有别于其他类群昆虫；不支持将大蜻亚科上升为科的观点；支持将大蜓科和蜓科归入蜓总科，而将春蜓科上升为总科的观点；差翅亚目5科之间的进化关系由慢到快依次为：春蜓科→大蜓科→蜓科→伪蜻科→蜻科。

Finally, I apply the concepts of dragonfly's biotopes to Kanding ecological park. Various types of lentic and lotic freshwaters surrounded by abundant hydrophytes and multi layers trees are planned. Besides, ecological landscape design with construction proceeds in terms of the following aspects: site gradation and sewage system, circulations and land use, plantation types and materials, and ecological construction methods with waterfront design details.

最后应用蜻蜓生物托邦之概念於崁顶生态公园，其生态地景设计在规划层次上考虑不同型态之流水与止水域空间的配置以及复层密林植被与丰富之水生植物的应用；并且从整地与排水、土地使用区分与动线系统、植被类型与植材选定、生态工法与亲水细部构想进行设计与营造。

Upon the disclosure of the plan, three companies were identified in the holding list of the group including Maniform Knitwear Co.,Ltd, Red Dragonfly Shoes Group and

近日，本土百货零售老大--大商股份公布改制方案，方案曝光的同时，曼妮芬针织、红蜻蜓鞋业及波司登三家企业浮出水面，赫然出现在其持股名单之列。

With i iration from nature and some help from research at the Ma achusetts I titute of Technology （news - web sites）, a team led by Carnegie Mellon engineering profe or Metin Sitti built a tiny robot that can walk on water, much like the i ects known as water skimmers or Jesus bugs.

受大自然灵感的启发和在美国马萨诸塞理工学院研究人员帮助下，美国Carnegie Mellon大学工程学教授Metin Sitti领导的团队，试制成功了世界上第一台能在水上行走的微型机器人，它犹如水上蜻蜓类的昆虫动物。

The study can provide the relative basis for molecular phylogeny study of Odonata.

结论］为蜻蜓目分子系统学研究提供相关依据。

This web site provides some images and an annotated checklist of British and Irish Odonata, and also includes related information of British Dragonfly Society research and recording projects.

该网站提供英国和爱尔兰蜻蜓目的一些图片和相应的注释一览表，同时网站还包含有该学会研究和记录项目的相关信息。

Two independent molecular sources were used to reconstruct phylogeny: the 16S rRNA gene on the mitochondrial genome and the 28S rRNA gene on the nuclear genome. A comparison of the sequences showed that the obtained 28S rDNA sequences have evolved at a much slower rate than the 16S rDNA, and that the former is better than the latter for resolving deep branching in the Odonata.

两种独立的分子资源用于重建系统发育发展史：线粒体基因组的16s rRNA基因和核基因组的28s rRNA序列比对表明：获得的28s rDNA序列以远低于16s rDNA的速率进化，并且28s rDNA比16s rDNA更适于分析蜻蜓目的深度分支。

Damselfly is the common name for any of the predaceous insects comprising the suborder Zygoptera of the order Odonata, characterized by an elongated body, large multifaceted eyes that are widely separated, and two pairs of strong transparent wings, which at rest typically are held folded together above the abdomen or held slightly open above the abdomen.

蜻蛉 蜻蛉俗称&豆娘&，学名&Ischnura heterosticta&。&蜻蛉&是一个通用名称，指的是任何带有蜻蜓目均翅亚目特征的肉食昆虫。这种昆虫体型细长，复眼较大且间距较宽，同时长有强壮而透明的翅膀——典型特征为折叠在腹部之上或在腹上微微张开。

Especially it can kill the pests who against agricultural chemical,and can properly protect the natural enemies of pests such as the ophis cocoon, bee, dragonfly, mantis, black spider etc.

尤其是可以杀死有抗药性的害虫，而且能切实保护害虫天敌，如蚕茧，蜜蜂，蜻蜓，螳螂，黑蜘蛛等，平衡自然生态。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
