Results Ten essential characteristic components have been identified in thirteen batches of Amomum villosum samples, and their relative content was (88.15±2.97)%, which are the representative components. The main components were α-pinene, camphene,β-pinene,β-myrcene, limonene, linalol, camphor, isoborneol, borneol and borneol acetate.

龙文化乃华夏民族的"根文化"，石文化乃是人类的"母体文化"，古往今来，二者就难以割舍，石是展示龙文化的最好载体之一。深扎于国人文化灵魂深处的龙与穿越了时空的石在龙岗的相遇将造就一场文化盛宴。

As to the formation and evolution of the motives in classical fictions, our viewpoints are: the FuXi custom had engendered an extremely rich repertory of motives, such as JianDi pregnancy legend in the Shang Dynasty, which was the earliest form of the "Swan Maiden" type stories in the world. This type of the story later in the Jin Dynasty evolved into the Maiden-bird type story, which again involved into many other stories in which maidens took the shape of an egret, a swallow, a snail, a tigress, a fairy maiden or a girl in lotus leaves. The custom of HanShi or QingMing may be embodied in the stories about encountering with a girl reviving from a tomb. The dragon in classical fictions may be disguised into an ox or trees, whose fight on fifth of May was a counterevidence of DuanWu.

至于古小说母题的生成和演化方面，我们也许可以认识到：以上巳为主的祓禊风俗产生了最为丰富的小说故事母题，如殷商时期的简翟生子传说是世界上最早的"天鹅处女"型故事，它在晋代又演化为女鸟故事；而那些鹤女、鹄女、鹭女、燕女、螺女、虎女、荷衣女等故事，则在不同程度上是"天鹅处女"型故事的变型型式；在同异境女子遇合的故事中，郑交甫神遇江妃二女、世间男子巧遇仙境女子的故事都包藏着上巳习俗的内涵，而幽婚故事更多地带有寒食、清明风俗的痕迹；古代盛传的金牛故事、青牛故事不但可以归属龙类故事，而且在很大程度上与端午厌胜蛟龙的巫术有关，至于龙斗故事则明显地和端午习俗相联系，甚至可以由此反证端午驱龙的本意。

But if feathers truly are the diagnostic criterion, then perhaps things should be the other way round, and Stegosaurus, Triceratops, Diplodocus, Tyrannosaurus and their kin should no longer be thought of as terrible lizards, but as overweight, flightless birds.

但是如果将羽毛作为评判的标准，那么也许事情应该是另一个样子：剑龙、三觭龙、梁龙，暴龙和他们的亲戚不应该再被想像成可怕的蜥蜴，而是被当做超重而无法飞行的鸟。

The result, once natural selection had done its work over the course of millions of years, was the now familiar cast of Allosaurus, Diplodocus, Triceratops and Tyrannosaurus rex.

自然界历时数百万年，完成了其优胜劣汰的工作，才得到如今这耳熟能详的演员阵容：异特龙、梁龙、三角龙和霸王龙。

There are six kinds of Dracaena in China. Dracaena cambodiana Pierre ex Gagnep is peculiar in Hainan province.

龙血树属植物我国产6种，其中海南龙血树（Dracaena cambodiana Pierre ex Gagnep）又名小花龙血树，是海南的特有树种。

In chapter 2, the contents of loureirins in the roots, stems and leaves of Dracaena cochinchinenis were analyzed by HPLC. On the other hand, using the preparation chromatography technology, five compounds were isolated from the leaves of Dracaena cochinchinenis, their structures were identified by means of spectral and chemical methods. They are steroidal saponins.

第二章主要是利用HPLC技术对剑叶龙血树根、茎、叶中龙血素成分的分析与探讨，并利用制备色谱等技术对剑叶龙血树叶子组成成分进行了分析、研究，得到化合物5个，经波谱鉴定，这5个化合物均是幽体皂贰类化合物。

In the present experiment, the tender stems of Dracaena cambodiana were used as explants to establish a two-step tissue culture and regeneration system. The effects of types and concentrations of plant hormones on the induction of callus were studied. Based on these, the reactions of callus regeneration to different mutation-induced approaches (60Co irradiation, EMS and colchicines), the regeneration ability of the treated callus as well as the characters diversities (including the appearance traits and cytological observations) of the regeneration plants were investigated.

本试验以龙血树幼嫩茎段为材料，通过对龙血树幼嫩茎段两步培养法再生的研究，建立了龙血树幼嫩茎段离体再生体系，证明了愈伤组织的发生和激素种类与浓度的关系；并在此基础上研究了愈伤组织再生对不同人工诱变方法（60Co辐射、EMS、秋水仙素）的反应、被处理愈伤组织再生能力和再生植株性状多样性、以及再生植株不同生理角度的变异性，得到了2株变异株系。

Amazing footage of striking snakes, forked tongued Komodo dragons, and the Gliding Dragon who literally flies from tree to tree in the Malaysian rainforests helps to piece together the worldwide legend of the Dragon.

本片摄制队会走访非洲的沙漠、亚洲及澳洲的雨林，找寻传说中龙的后代，并去发掘巨蜥、鳄鱼、蜥蝪及蛇生理上及习性上与龙的异同，从而更加了解龙这种传说中的动物。

With an ear-splitting dragon roar, that two people are hit down badly by Long-shen-goon and Po, who is in dragon-shadow shape, submerges into the woods beside the path.

可是已然不及，只听得一声震耳的龙啸，那两个族人被龙神功撞成重伤倒地，化身龙影的童博没入路旁林中消失了

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
