本文论述了23科，即虎甲科、步甲科、牙甲秒、隐翅虫科、龙虱科、叩头虫科、葬甲科、阎甲科、陷附郭公虫科、吉丁虫科、谷盗科、露尾甲科、方头甲科、扁甲科、锯谷盗科、小覃甲科、薪甲科、蛛甲科、长蠹科、窃蠹科、粉蠹科、拟步甲科、芫菁科共87种。

This thesis focuses on beetle Cybister tripunctatus in addition to some other species of beetles and studied the elytron's micro-structure. We found that there are many concaves、hollows and holes on its structure; the configuration of this material is compound samdwich; the linkage-structure between elytra adopts the concave-protuberant mesh joint with some bristle.

本文以东方龙虱为重点研究对象，并综合了四个科的十个物种，通过对甲虫鞘翅微结构的观测，发现东方龙虱鞘翅表面遍布着很小的凹坑；从其鞘翅断面来看，内部存在着许多空腔和孔道结构，而且甲虫鞘翅是复合层状结构；对鞘翅间联接处研究发现，联接机构采用了凹凸啮合结构，在局部区域存在微小毛刺和突起结构来增加摩擦接触。

Namely,spinous setae mainly distributed on the legs of Cybister bengalensis,acetabula setae distributed on the legs of male Cybister bengalensis,and bunchy setae only distributed on the nick points of the pronotum and the elytra.

采用体视显微镜、扫描电镜技术观察并描述了黄缘真龙虱体壁表面各部位的形态结构特征，发现了3种典型的凹陷和普遍存在的凸起，了解了其三维结构，分析了凹陷与龙虱水生生活的关系。

After testing the mechanical property of elytron with nanoindentation, the experiment result shows that values of Cybister tripunctatus's elytron chitin are higher than the average values, and the mechanical property of different testing areas are dissimilar.

在对多种甲虫鞘翅运用纳米压痕仪进行力学性能测试后，发现东方龙虱鞘翅壳质层的力学性能数值要大于总体的平均值，而且同一甲虫鞘翅的不同测试区的力学性能也存在差异。

The other typical non-smooth surface morphology structures of Cybister bengalensis,including ripple and squama and so on,were observed.

同时，发现了龙虱体表存在的其他如波纹、鳞片等典型非光滑形态结构，测定了体壁水接触角，探讨了这些结构与水中运动减阻功能的关系。

The surface morphology structures of Cybister bengalensis were observed and depicted by stereo-microscope and scanning electron microscopy.The results indicated that three typical concaves and universal heaves exist.

In the market, often mixed with Dytiscidae sold for human consumption.

在市场上常混入龙虱中出售，以供食用。

As a pond in the common Daya A, about 32-35m, black The shiny, look like large Dytiscidae, but the back of the arch; in the chest and abdomen with thick vertical plate central uplift backward prominent spikes was like, can be with distinction.

如池沼中常见的大牙甲，长约32—35m，漆黑而有光泽，外表似大型龙虱，但背面拱起；中胸腹板中央有粗壮的纵隆起，向后突出呈尖刺状，可与之区别。

The morphology structures in different parts of surface setae were observed and compared.And three typical categor...

The water beetle, also known as the "predacious diving beetle", is often fried with garlic and ginger and sold as a side dish.

水甲虫，又称&龙虱&，经常油炸后佐以大蒜和姜作为小菜卖。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
