The study on microstructure characteristics of the five pores on the surface of ostracoda at Nenjiang Formation of Songliao Basin in Cretaceous shows that during the depositional period of Nenjiang Formation in Cretaceous,Songliao Basin should be a continental depositional system and palaeolacustrine enviroment and furthermore its water body property should be fresh saltish.

本文对松辽盆地白垩纪嫩江组介形类化石壳体表面毛细管孔的显微构造特征研究表明，白垩纪嫩江组沉积时期，松辽古湖盆应为一陆相沉积体系，其水体性质应为淡水—少盐水的古湖泊环境。

Stable isotopic composition of fossil ostracode is used as an ideal proxy for paleo-lake sedimentary environments.

介形虫化石壳体被认为是反映古湖泊沉积环境的理想对象。

From the aspect of the EF per-capita supply and demand structure, the conflict outstood between demand and supply of cropland and fossil fuel land. The deficit of pasture and fishing ground were relatively small in Guangdong. There were partial woodland surplus before the year 2000. Though it is balanceable between the demand and supply of building land, the ratio in per capita total EF was much higher, and the structure of different type of land is not rational.

从人均生态足迹的供需结构看，耕地和化石燃料用地的供需矛盾非常突出，草地和水域赤字相对较少，林地在2000年之前还有部分盈余，而建设用地虽然供需平衡，但是其占人均总足迹的比例偏大，各种土地类型构成不太合理。

The first penguin fossil to be discovered was that of Palaeeudyptes antarcticus, found in rocks that were around 25 million years old, in New Zealand during the 19th century.

第一个企鹅化石是南极的Palaeeudyptes 的那一个。是19世纪时在新西兰距今大约有两千五百万年的岩石中发现的。

The environmental palaeobotany, one of new research fields in palaeobatany, investigates palaeovegetation succession, discusses internal relations of fossil plants-environment and reconstructs change of palaeoclimate and palaeoenvironment through geological time.

环境古植物学是古生物学中一个新的研究领域，它探讨地质历史时期古植被的演替、化石植物与环境之间的内在联系，恢复地史时期的古气候与古环境。

The specific laboratories affiliated to the state key laboratory are well equipped to support researches in palaeobotany, structural botany, cytology, protein analysis, structural genomics, and functional genomics, etc.

专业实验室有大化石实验室、结构植物学实验室、细胞学实验室、蛋白质组学实验室、结构基因组学实验室、功能基因组学实验室、实验温室和相片制作室等。

In this paper, the author discovered Solenites murrayana L. et H. from Yaojie Formation of Middle Jurassic which was an important species of Ginkgophytes in Mesozoic during environmental palaeobotany study of Lanzhou-Minhe Basin. The epidermic structure of Solenites murrayana in Yaojie Formation is similar to that of Solenites murrayana in Yorkshire Jurassic of UK by cuticular analyses.

作者在兰州-民和盆进行环境古植物学的研究中，于中侏罗统窑街组发现了中生代银杏类植物化石的重要代表穆雷似管状叶Solenitesmurrayana L.et H。，通过分析S.murrayana的表皮构造，得出与英国约克郡侏罗纪的S.murrayana具有明显相似性的特点。

This number is "very conservative" and could be as high as 11 metres, Greene says, which would lower the corresponding temperature estimate for the Palaeocene tropics.

这个数据很保守，也可能是11米，格林尼说，这将有可能降低古新世时代热带地区的气候。呵呵，明明是蛇化石，你却只说&蛇&，把大家都骗进来了。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
