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。

Over the last three decades, measurements of the δ^13C andδ^18O values of ostracode shells have been extensively used in lake palaeoenvironmental reconstruction.

Results A total of 121 positive clones were randomly screened from the library and 22 Operational Taxonomic Units were determined. BLAST analysis indicated that all OTUs were affiliated with the phylum Crenarchaeota.

从冷泉沉积物古菌16S rRNA 基因文库中随机挑选了121个阳性克隆，共得到22个不同的可操作分类单元，BLAST结果表明全部克隆子归属于泉古菌门中免培养类群。

They have several meters of paleosol developed on the top of overbank silt, suggesting that the abandonment of each terrace due to river incision occurs during the transition from glacial to interglacial climates and there may be a link between the production of terraces and glacial-interglacial climatic cycles. However, it is not every glacial-interglacial transition during the last 1,240ka that terrace can form and preserve.

黄河各阶地河漫滩顶部都有一层古土壤发育表明黄河下切形成阶地发生在古土壤开始发育的冰期向间冰期的过度阶段，但是并非1，240ka以来的每次冰期—间冰期的气候交替都能引起黄河下切形成阶地。

Now, in a breakthrough described as the classical equivalent of finding the holy grail, Oxford University scientists have employed infra-red technology to open up the hoard, known as the Oxyrhynchus Papyri, and with it the prospect that hundreds of lost Greek comedies, tragedies and epic poems will soon be revealed.

牛津大学的科学家运用远红外技术揭开了被称为埃及奥斯莱卡浦草纸古卷的文物，这一突破性的成果被称为和发现圣杯的意义一样重大，这意味着几百部遗失的古希腊喜剧、悲剧和史诗即将重现天日。
