侏罗纪

The fern Adiantum capillus-veneris has an unconventional photoreceptor, phytochrome 3 (phy3), which is a chimaera of the red/far-red light receptor phytochrome and phototropin.

光敏色素-3的生成，可能是在第三纪和侏罗纪之间致密森林出现时使得蕨类植物能够适应黑暗环境的一个关键演化步骤。

In th e Late Jurassic the Central Atlantic Ocean was a narrow ocean separating Afric a from eastern North America.

晚侏罗纪，随着非洲陆块从北美陆块的分离，中间形成了一条狭窄的大洋，即是今天大西洋的中心。

Allosaurus was the top predatory dinosaur of the late Jurassic period in North America.

异龙是最大的掠夺性恐龙的晚侏罗纪期间在北美地区。

The Monster of Minden'' is a badly-documented late-Jurassic specimen from the Wiehengebirge, Germany. The German edition of National Geographic for November 1999 contains an article in which this animal's ribs are described as 1.5 times as large as those of Allosaurus, and its teeth are claimed to be a foot long including the root.

从明登来的达斯怪兽""明登怪兽是一种后侏罗纪的生物，来自德国的威亨格布裏尔格的化石标本支离破碎。1999年11月份的德文版国家地理杂志刊登了一篇文章，文章中描述了这种生物的肋骨长度是与它类似的侏罗纪恐龙的肋骨的1.5倍，它的牙齿据称有一英尺长。

In Jurassic-Paleogene, the West Kunlun, West Tianshan, Tarim and the Central Asia exhibited a relatively quiet period after the orogenic movement. Due to extension, these area displayed peneplain tectonic geomorphologic landscape.

侏罗纪，西昆仑、西天山、塔里木大陆及中亚—带都处于造山期后的相对宁静期，以仲展构造作用为主，主要表现为准平原化的构造地貌景观，沉积有高成熟度的侏罗纪含煤岩系，塔西南表现为陆内伸展盆地，这一时期可持续到早第三纪。

Photo Gallery: Jurassic Period The late Jurassic Stegosaurus, like the pair walking through a North American forest in this illustration, was a slow-moving, plant-eating dinosaur that grew as long as 30 feet (9 meters) and as much as 2 tons.

侏罗纪时代图片集。晚侏罗纪古生剑龙，像一双穿过北美森林在这方面的插图，是一个缓慢的移动，恐龙吃植物的增长体长要在30英尺（ 9米）和重达2吨。

It is very difficult to get any suitable result on the basis of genus, or higher taxon in studying Jurassic bivalve palaeobiogeography.

聚类分析结果以及对控制藏北、藏南和印度侏罗纪双壳类动物群分布因素的分析表明，侏罗纪时，藏南地块的位置更靠近藏北地区，而距印度次大陆较远，与前人认识不同。

Genus and 40 species of Jurassic Pteriomorphia and Isofilibranchia from Northern Tibet were described in present paper. The data of genus and species of Jurassic Pteriomorphia and Isofilibranchia from Northern Tibet, Southern Tibet, and India were studied with cluster analysis respectively. The Jurassic palaeobiogeographic and palaeogeographic relations of these three regions were also discussed on the basis of the result of cluster analysis and analysis of the controlling factors of bivalve distribution.

本文记述了藏北侏罗纪双壳类Pteriomorphia和lsofilibranchia化石22属40种，对藏北、藏南及印度侏罗纪Pteriomorphia和Isofilibranchia的属和种分别进行了统计和聚类分析，以此探讨这三个地区之间的古生物地理关系，并进一步分析了控制侏罗纪双壳类分布的因素及讨论了藏北、藏南与印度这三大地块的古地理位置。

One earlier variety of the granites, provisionally termedas Kushan Granite, is coarser-grained, often flesh-colored, and biotite-bearing,similar in character to the most frequently seen and widely distributed graniteof whole Fukien; the other, the Kueichi Granite, often intruding into the firstnamed, is colored by different shades of grey, mostly, fine-grained, and mia-rolitie, containing minor amount of hornblen...

从二者产生状态看来，彼此生成时间甚为接近，而同属於太平洋运动产物，分属早晚期活动。再根据前人各种地质文件，推论出福建各地普遍存在着相当於这两种侵入的花岗岩类岩石。因此，联系到福建后侏罗纪金属矿成矿作用的多次性可能。这在江西西华山已有发现。此后从多次性来研究后侏罗纪的炎成矿床的成矿作用，成为必要了。

The ice raft and the glacier mud rock flow deposited along the northern and northwest edge of the plateau during early Cretaceous, implies that the northern edge of the plateau may be of the suitable height, may be similar to present＇s Himalaya Mountain.

该区中生代构造特征表明，该区侏罗纪和早白垩世的构造特点有着巨大的差异：侏罗纪，尤其是晚侏罗世末期以南北向的挤压构造为主，而早白垩世中期以后演变为以伸展构造为特征，古地理古环境明显改变。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
