侏罗纪末～早白垩世初的火山活动除有熔岩（146Ma，137Ma）喷出外，还发育有辉长岩侵入体（135Ma）和辉绿岩岩墙（129Ma）等次火山岩。

A Living Fossil Fish: The arapaima is a true prehistoric river monster, with the fossil record showing that it has roamed the waters of the Amazon River since the Jurassic age.

Ross: And that should conclusively prove that I had the idea for Jurassic Park first!

最终这就证明了是我先想出来侏罗纪公园这个主意的！

Did you know Cycas is the most primitive gymnosperm, having existed since Jurassic times and undergone little change in its appearance and features for 200 million years.

导赏资料：苏铁是最原始的裸子植物，在侏罗纪时代已经存在，外形及其他特徵在二亿年来均没有太大改变，所以又称为「活化石」。

They've hardly changed their forms since the Devonian and Jurassic periods.

自泥盆纪和侏罗纪时期以来，它们就没有改变过身体的外形。

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。

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。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
